  1. 8-channel Bi-directional Logic Level Converter - TXB0108

    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!
  2. 4-channel I2C-safe Bi-directional Logic Level Converter - BSS138

    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. 

  3. Logic Level Converter

    This logic level converter is a small device that safely steps down 5V signals to 3.3V and steps up 3.3V to 5V. This level converter also works with 2.8V and 1.8V devices.
