16.05 X 13.33mm Logic Level 4 Channel I2c Bi-directional Converter

This Level Converter- 4 Channel features four high speed bi-directional 4 channels, allowing for safe and easy communication between devices operating at different logic levels. Recommended to use with Arduino Due, Raspberry pi and any board that has 3.3v logic levels.

The board needs to be powered from the two voltages sources (high voltage and low voltage) that your system is using. High voltage (5V for example) to the HV' pin, low voltage (3.3V for example) to LV', and ground from the system to the GND pin.

Features:
Connects a 3.3V device to a 5V system
Steps down 5V signals to 3.3V AND steps up 3.3V to 5V simultaneously
This level converter also works with 2.8V and 1.8V devices
Sets high and low voltages and step up and down on the same channel
Each level converter has the capability of converting 4 pins on the high side to 4 pins on the low side with two inputs and two outputs provided for each side
Dimensions:0.63" x 0.52" (16.05 x 13.33mm)
