A small, but very mighty power supply. This board was designed to be as small and inconspicuous as possible. The nice thing about LiPower is the ability to use rechargable Lithium Polymer batteries. These batteries are smaller, flatter, and last much longer than a AAA battery. Attach a single cell LiPo battery, flip the power switch, and you will have a 5V supply to power your LilyPad network. Good up to 150mA. Short circuit protected.

This board has a JST connector, which will connect to our JST terminated single cell 3.7V LiPo batteries. It also has terminals for charging the LiPo battery with one of our LiPo chargers.

LilyPad is a wearable e-textile technology developed by Leah Buechley and cooperatively designed by Leah and SparkFun. Each LilyPad was creatively designed to have large connecting pads to allow them to be sewn into clothing. Various input, output, power, and sensor boards are available. They're even washable - but be sure to remove the battery!

Note: A portion of this sale is given back to Dr. Leah Buechley for continued development and education of e-textiles.

Surface transducers give you the awesome power to turn almost any surface into a speaker. Much like our larger surface transducer, this is essentially just a speaker except instead of a cone, the coil is attached to a pad that conducts the vibration into whatever you press it against. You can hook it up to an audio source and press it against the nearest table, wall or cardboard box. You can even put it against your head and play music directly into your skull (the ultimate surround sound).

This one is really small. About the size of a 1 € coin.

Note: The connectors on these units are somewhat fragile so take care to prevent stressing your connection to the unit.

This is a simple to use USB AVR programmer. It is low cost, easy to use, works great with AVRDude, and is tested extensively on a Windows desktop. Based on Dick Steefland's USBtiny and Limor Fried's USBtinyISP.

We've gotten a big response (see comments and forum posts below) from Mac and Linux users having problems. We use this programmer extensively on a Windows box and love it.
However, this is a low-cost programmer designed for those on a tight budget. For out-of-the-box compatibility with other operating systems and machines, checkout the AVR ISP2 USB programmer from Digikey.

This programmer works really well for ATmega168 and ATmega328 and should work with all the AVR micros supported by AVRDUDE. We've played a bit with the ATtinys but we cannot guarantee that this board will be compatible with anything but ATmega168/328.

This board is buffered and power protected so that you can do some really evil things to the programmer without killing it. It is fast! Comparable speed to the AVR ISP2 USB programmer from Digikey. One of the greatest features of this board is the ability to power the target (up to 500mA) from the programmer.

To use this programmer, attach to a Windows machine and install the drivers listed below. Open a command prompt. Assuming WinAVR(and therefore AVRDUDE) have been installed, type:

avrdude -c usbtiny -B 1 -patmega328 -U flash:w:main.hex

Be sure to include the "-B 1" flag as this will significantly increase the programming speed! You may need to change -p flag to your appropriate microcontroller. You can setup a tool and hotkey in Programmers Notepad to do this automatically.

Features:

• Standard AVR ISP programmer
• ATtiny2313 with USBtiny firmware preloaded
• Buffered output
• PTC fuse protected power
• Programmer can power target
• Supports ATmega168/328 and many others
• Two status LEDs
• Both 10-pin and 6-pin targets supported (cable included)

Documents:

• Schematic
• Windows Driver

Open Source Hardware: We like to share. The original engineering files are available for mass hackery.

• Firmware based on USBtiny (type 'make all' in the spidirectory). I've found that the compile only works with older versions of WinAVR (20080430).

This is a breakout board for Freescale's MPR121QR2. The MPR121 is a capacitive touch sensor controller driven by an I2C interface. The chip can control up to twelve individual electrodes, as well as a simulated thirteenth electrode. The MPR121 also features eight LED driving pins. When these pins are not configured as electrodes, they may be used to drive LEDs.

There a four jumpers on the bottom of the board, all of which are set (closed) by default. An address jumper ties the ADD pin to ground, meaning the default I2C address of the chip will be 0x5A. If you need to change the address of the chip (by shorting ADD to a different pin), make sure you open the jumper first. Jumpers also connect SDA, SCL and the interrupt pin to 10k pull-up resistors. If you don't require the pull-up resistors you can open the jumpers by cutting the trace connecting them.

There is no regulation on the board, so the voltage supplied should be between 2.5 and 3.6VDC. The VREG pin is connected through a 0.1uF capacitor to ground, which means, unless you modify the board, you can't operate the MPR121 in low-supply voltage mode (1.71-2.75VDC).

This is similar to other 16x2 character LCDs that you've seen before but with one vibrant difference: The backlight is actually an RGB LED. This means that you can change the backlight of this display to any color you want by controlling the three backlight levels. It also utilizes an extremely common parallel interface so code is freely available (check below for an Arduino example). You will need ~11 general I/O pins to interface to this LCD screen, plus an extra 3 pins for the RGB backlight.

Note: The backlight is controlled by pins 18, 17, and 16.

This is the latest evolution of Sparkfun's serial LCD. Included on a single board is a 16x2 LCD and an embedded circuit based around a PIC 16F88. The on-board PIC takes a TTL serial input and prints the characters it receives onto the LCD. The installed firmware also allows for a number of special commands so you can clear the screen, adjust the backlight brightness, turn the display on/off, and more.

Communication with SerLCD requires 5V TTL serial at a default baud rate of 9600bps (8-N-1). You can adjust the baud to any standard rate between 2400 and 38400bps. The power (VDD), ground (GND) and RX pins are all broken out to both a 0.1" pitch header as well as a 3-pin JST connector.

SerLCD has the ability to dim the backlight to conserve power if needed. There is also a potentiometer on the back of the display to adjust the contrast.

Features:

• Embedded PIC 16F88 utilizes onboard UART for greater communication accuracy
• Adjustable baud rates of 2400, 4800, 9600 (default), 14400, 19200 and 38400
• Operational Backspace
• Greater processing speed at 10MHz
• Incoming buffer stores up to 80 characters
• Backlight transistor can handle up to 1A
• Pulse width modulation of backlight allows direct control of backlight brightness and current consumption
• All surface mount design allows a backpack that is half the size of the original
• Faster boot-up time
• Boot-up display can be turned on/off via firmware
• User definable splash screen

Conductive thread is a creative way to connect various electronics onto clothing. This thread can carry current for power and signals. While not as conductive as traces on a printed circuit board (PCB), this thread makes wearable clothing 'wearable'!

This thread is stainless steel making it extremely tarnish resistant. This thread is a 6-ply thread making it thicker with the ability to conduct much more power. It is often laid on a fabric and then held in place with a over-stitch (sometimes called a couching stitch) of non-conductive machine sewable thread.

What can you do with more power? Keep your hands warm! This thread has been used in gloves, vests, and clothing as a heater coil.

The extra thick thread has an extremely low resistance of about 1.4 Ohms per linear foot and weighs about 0.93 ounces for the full 50 feet.

The Wireless SD shield allows an Arduino board to communicate wirelessly using a wireless module. It is based on the Xbee modules from Digi, but can use any module with the same footprint. The module can communicate up to 100 feet indoors or 300 feet outdoors (with line-of-sight). It can be used as a serial/usb replacement or you can put it into a command mode and configure it for a variety of broadcast and mesh networking options. The shields breaks out each of the Xbee's pins to a through-hole solder pad.

Included on board is a SD card slot. When using the SD Library to access the card, Pin 4 is CS and cannot be used otherwise. SPI also relies on pins 11, 12, and 13 for communication.

Also on board is a switch allowing for control via USB or the microcontroller.

These motorized sliders are very cool. Each is essentially a standard slide pot which is belt-driven by a small motor. The slide contains two separate 10k audio taper potentiometers so that you can use one as servo-feedback in order to read the position of the slider and use the other to control whatever your target is. There is also a touch sense line which is electrically connected directly to the metal slider tab so that you can interface the slider with capacitive touch circuitry.

Motorized potentiometers are useful when you need the ability to jump to preset positions or when you want physical feedback from virtual controllers. There are also a variety of unconventional uses for these potentiometers such as pulsing the motor to provide haptic feedback or just using it as a linear actuator for super light-duty robotics.

Comes with a black slider knob.

This is a piezoresistive force sensor. The harder you press, the lower the sensor's resistance. Pressing hard, the resistance changes from infinite to ~300k. The sensor itself is thin and flexible, but the resistance does not change while being flexed. Resistance changes only when pressure is applied to the round area at the end of the sensor. Used as a presence sensor (someone standing), weight sensor, pressure sensor (impact testing), etc.

The overall length is about 8.5". Sensor comes with 0.1" spaced, reinforced, breadboard friendly connector.

This sensor comes in three flavors. This sensor ranges from 0 to 1 lb of pressure.

This is the new Arduino Uno R3. In addition to all the features of the previous board, the Uno now uses an ATmega16U2 instead of the 8U2 found on the Uno (or the FTDI found on previous generations). This allows for faster transfer rates and more memory. No drivers needed for Linux or Mac (inf file for Windows is needed and included in the Arduino IDE), and the ability to have the Uno show up as a keyboard, mouse, joystick, etc.

The Uno R3 also adds SDA and SCL pins next to the AREF. In addition, there are two new pins placed near the RESET pin. One is the IOREF that allow the shields to adapt to the voltage provided from the board. The other is a not connected and is reserved for future purposes. The Uno R3 works with all existing shields but can adapt to new shields which use these additional pins.

Arduino is an open-source physical computing platform based on a simple i/o board and a development environment that implements the Processing/Wiring language. Arduino can be used to develop stand-alone interactive objects or can be connected to software on your computer (e.g. Flash, Processing, MaxMSP). The open-source IDE can be downloaded for free (currently for Mac OS X, Windows, and Linux).

Note : The Arduino Uno R3 requires the Arduino 1.0 drivers folder in order to install properly on some computers. We have tested and confirmed that the R3 can be programmed in older versions of the IDE. However, the first time using the R3 on a new computer, you will need to have Arduino 1.0 installed on that machine.  If you are interested in reading more about the changes to the IDE, check out the official Arduino 1.0 Release notes.

Features:

• ATmega328 microcontroller
• Input voltage - 7-12V
• 14 Digital I/O Pins (6 PWM outputs)

The Arduino Ethernet Shield allows an Arduino board to connect to the internet. It is based on the Wiznet W5100 ethernet chip (datasheet). The Wiznet W5100 provides a network (IP) stack capable of both TCP and UDP. It supports up to four simultaneous socket connections. Use the Ethernet library to write sketches which connect to the internet using the shield. The ethernet shield connects to an Arduino board using long wire-wrap headers which extend through the shield. This keeps the pin layout intact and allows another shield to be stacked on top.

The latest revision of the shield adds a micro-SD card slot, which can be used to store files for serving over the network. It is compatible with the Arduino UNO, Arduino Duemilanove and Mega (using the Ethernet library). A separate power-over-Ethernet (PoE) module is soldered to the board to provide power from a conventional twisted pair Category 5 Ethernet cable. It is IEEE802.3af compliant.

The Arduino Ethernet is a microcontroller board based on the Arduino Uno, and incorporating a WizNet W5100 TCP/IP Embedded Ethernet Controller. It can be programmed like an Uno via a six-pin FTDI -style serial connector. The Arduino USB-to-Serial adapter or any FTDI-style USB-to-serial connector can be used to program it.

A separate power-over-Ethernet (PoE) module is soldered to the board to provide power from a conventional twisted pair Category 5 Ethernet cable. It is IEEE802.3af compliant, and works with all compliant PoE injectors currently available.

The Arduino ADK is a microcontroller board based on the ATmega2560 (datasheet). It has a USB host interface to connect with Android based phones.

Solenoids are a great way to induce linear motion for pushing, pulling or controlling switches and levers. According to the datasheet this solenoid is rated for 36V but they work like a charm at 12V. With a throw of 10mm these solenoids are great for all kinds of motion applications such as actuating door latches, automating percussion instruments or just poking people.

Note: The datasheet indicates a throw of 25mm however Sparkfun measured a throw of 10mm.

This new revision of the MP3 player shield retains the awesome MP3 decoding abilities of the last version but adds the storage functionality of the SD card shield. Now you can pull MP3 files from an SD card and play them using only one shield, effectively turning any Arduino into a fully functional stand-alone  MP3 player! The MP3 Shield still utilizes the VS1053B MP3 audio decoder IC to decode audio files. The VS1053 is also capable of decoding Ogg Vorbis/MP3/AAC/WMA/MIDI audio and encoding IMA ADPCM and user-loadable Ogg Vorbis.

The VS1053 receives its input bitstream through a serial input bus (SPI). After the stream has been decoded by the IC, the audio is sent out to both a 3.5mm stereo headphone jack, as well as a 2-pin 0.1" pitch header.

This shield comes populated with all components as shown in the images and schematic; but it does not come with headers installed. We recommend the Stackable Header Kit.

Note: Please refer to the Line Out document below for important information regarding connecting this shield directly to an amplifier.

This new version corrects the pin out for the GPX and RESET pins. The USB Host Shield contains all of the digital logic and analog circuitry necessary to implement a full-speed USB peripheral/host controller with your Arduino. This means you could use your Arduino to interface with and control any USB slave device - thumbdrives, digital cameras, bluetooth dongles, and much more!

A four-wire serial interface is used to communicate with the host controller chip, so the shield connects the Arduino's hardware SPI pins (D10-13) to the MAX3421E. A USB type A female connector is wired up to the IC, and it also supplies 5V as any normal USB port would.

The Host Shield takes its power from the 'Vin' pin on your Arduino. Power from that pin is regulated to both 5V and 3.3V on the shield. All SPI signals are sent through a hex converter to step them down to 3.3V.

Ever wonder what would happen if you stacked an Ethernet shield on an Arduino Pro microcontroller and ran over it with a steam roller? Well, it would probably just break. But in a cartoon world it might turn into the Ethernet Pro! The Ethernet Pro is an Arduino-sized, shield-compatible microcontroller with all of the functionality of the Ethernet shield built right in!

The Ethernet Pro is based on the same hardware as the Ethernet shield (Wiznet W5100) in the same configuration so it is a drop-in replacement for the "Arduino/Ethernet double-stack," and works with all of the existing Ethernet shield libraries and code. This board features the 'Optiboot' bootloader, so be sure to select "Arduino Uno" in the Arduino IDE when you program it. The board can be programmed using either an FTDI Basic or the ATmega8U2 breakout (w/ USB-to-Serial firmware).

The IOIO (pronounced "yo-yo") is a board specially designed to work with your Android device (OS versions 1.5 and greater). The board provides extensive and robust connectivity to an Android device via a USB connection. The IOIO is fully controllable from within an Android application, using a simple and intuitive Java API - no embedded programming or external programmer will ever be needed!

So far, the devices proven to work are: G1, Nexus One, Nexus S, Motorola Droid X. If you get the IOIO working on your Android device, please let us know in the comments below, thanks!

The IOIO board contains a single MCU that acts as a USB host and interprets commands from an Android app. In addition, the IOIO can interact with peripheral devices in the same way as most MCUs. Digital Input/Output, PWM, Analog Input, I2C, SPI, and UART control can all be used with the IOIO. Code to control these interfaces is written in the same way as you write an Android app with the help of a simple to use app-level library. In other words, you can combine the awesome computing power, Internet/Bluetooth connectivity, touch screen, and a variety of sensors from your Android device with the ability to easily add peripheral devices to interact with the outside world.

The board needs to be powered through the VIN pin with a 5V-15V power supply. There is also an optional, unpopulated JST connector footprint on the bottom of the board that can be used, however single cell LiPos will NOT work with this connector, you need a 5-15V input. More info here. The IOIO can also provide 1.5A at 5V for charging your Android device or powering small servos, etc.. A potentiometer on the board allows limiting the amount of current the Android device pulls for detection and charging. It needs to be adjusted once for a specific hardware model or be set so that full charging current is supplied. Be sure to enable USB debugging on your Android device to allow communication with the IOIO. More information on how to do all of this can be found in the Beginners Guide.

In order to write code to interact with the IOIO, you will need to download and install a few pieces of software, one of which is theAndroid SDK. If you are new to the IOIO or new to developing apps with Android, please use these resources to help get started:

• Example Projects

Using the IOIO does not require any hardware or software modifications to your Android device, thus preserving the warranty as well as making the functionality available to non-hackers. If you would like to modify the firmware on the MCU, the code is open-sourced and can be found here.

Update: The IOIO now has beta firmware available which supports Google's Open Accessory (ADK) protocol. The code base can be foundhere, although, keep in mind, the code is in beta and is intended for advanced users that have a PIC programmer. General information, including differences between ADK and the current ADB protocol, can be found here.

Gameduino is a game adapter for Arduino (or anything else with an SPI interface) built as a single shield that stacks up on top of the Arduino and has plugs for a VGA monitor and stereo speakers. The sound and graphics are definitely old-school, but thanks to the latest FPGA technology, the sprite capabilities are a step above those in machines from the past. The adapter is controlled via SPI read/write operations, and looks to the CPU like a 32Kbyte RAM. (Unlike many 8-bit machines, there are no restrictions on when you can access this RAM). There is even a handy reference poster (which you can download below) showing how the whole system works.

Do you ever wish your Arduino was more musically talented? Or maybe your project could use some cool sound effects. The Musical Instrument Shield is an easy way to add great sounding MIDI sound to your next Arduino project. This board is built around the VS1053 MP3 and MIDI codec IC, wired in MIDI mode. Simply connect a speaker/stereo/pair of headphones to the 1/8" stereo jack on the shied and pass the proper serial commands to the IC and you'll be playing music in no time!

The VS1053 contains two large tonebanks including various piano, woodwinds, brass, synth, SFX and percussion sounds. The shield is also capable of playing several tones simultaneously (maximum polyphony of up to 31 sounds!). Take a look at our example code to get an idea of how easy it is to add musical zest to your next Arduino gadget.

Note: The 3.3V regulator on this shield isn't properly loaded, so you may see 3.9V at the VS1053, which is not ideal. This should not cause any issues and we've found the board to work just fine under these conditions. We will be changing this for our next revision.

The Si4735 is the first digital CMOS AM/FM radio receiver IC that integrates the complete tuner function from antenna input to audio output. This feature-rich solution includes advanced seek algorithms, soft mute, auto-calibrated digital tuning, and FM stereo processing. The chip also incorporates a digital processor for the European Radio Data System (RDS) and the North American Radio Broadcast Data System (RBDS), including all required symbol decoding, block synchronization, error detection, and error correction functions. Basically it's an entire AM/FM, LW/SW radio in a single chip.

Now that we've mounted it on a shield, you can harness all of that sweet radio-playing power right from your Arduino. Simply stack the shield onto your Arduino board, plug in some speakers (headphones don't seem to work as well without a preamp) and use the library below to control the volume, channel selection, etc. The library also allows you to send a variety of other commands constructed by consulting the Si4735 Programmers Guide.

This board seems to get decent reception compared to other stereos around the office even using a simple wire antenna. If you happen to have an antenna that you'd like to use it can be soldered right to the via marked "antenna".
