IIC I2C Logic Level Converter Bi-Directional Module 5V to 3.3V
Allow your 5V and 3.3V logic components to play nicely together! It will also work with 2.8V and 1.8V devices.
You can set your high and low voltages and step up and down between them safely 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.
Simple to use. The board needs to be powered from the two voltage sources (high voltage and low voltage) that your system is using. High voltage (5V) to the ‘HV’ pin, low voltage (3.3V) to ‘LV’, and ground from the system to the ‘GND’ pin.
