The 3.3V SparkFun FT231X Breakout board, complete with the full UART hardware handshake feature! The pin-out of this board matches the FTDI cable to work with official Arduino and cloned 3.3V Arduino boards. It can also be used for general serial applications.14,00 €
When you need to amplify, filter, add, or otherwise manipulate analog signals you'll certainly want an operational amplifier at your side.3,25 €
CD40106BE consists of six Schmitt-trigger circuits. Each circuit functions as an inverter with Schmitt-trigger action on the input. The trigger switches at different points for positive- and negative-going signals.
Run four solenoids, two DC motors or one bi-polar or uni-polar stepper with up to 600mA per channel using the L293D.3,00 €
This level shifter board combines the ease-of-use of the bi-directional TXB0108 with an I2C-compatible FET design following NXP's app note.5,00 €
- This chip perform bidirectional level shifting from pretty much any voltage to any voltage and will auto-detect the direction. Only thing that doesn't work well with this chip is i2c (because it uses strong pullups which confuse auto-direction sensor). If you need to use pullups, you can, but they should be at least 50K ohm - the ones internal to AVRs/Arduino are about 100K ohm so those are OK!8,00 €
