4-channel I2C-safe Level Converter
4-channel I2C-safe Bi-directional Logic Level Converter
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.
Dimensions: 2.2 CM x 1.75 CM
