4 Channel IIC I2C Logic Level Converter Bi-Directional Module 5V to 3.3V

Product details of 4 Channel IIC I2C Logic Level Converter Bi-Directional Module 5V to 3.3V
If you've ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be.  logic level converter is a small device that safely steps down 5V signals to 3.3V and steps up 3.3V to 5V.  It is used with normal serial, I2C, SPI, and any other digital signal. Does not work with an analog signal.

This level converter also works with 2.8V and 1.8V devices. Each level converter has the capability of converting 8 pins on the high side to 8 pins on the low side. Two inputs and two outputs are provided for each side.
