Product details

Adafruit 4 Channel I2C-Safe Bi-Directional Logic Level Converter

• 4 BSS138 FETs with 10K pullups• Works down to 1.8V on the low side, up to 10V on the high side• Designed for I2C, but also works for SPI, TTL Serial, and any other digital interface both uni-directional and bidirectional
• Comes with a fully assembled and tested PCB
• 4 full bidirectional converter lines as well as 2 pieces of 6-pin header you can solder on to plug into a breadboard or perfboard

Because the Arduino (and Basic Stamp) are 5V devices, and most modern sensors, displays, flash cards and modes are 3.3V-only, many makers find that they need to perform level shifting/conversion to protect the 3.3V device from 5V.

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.
