2 Channel Name: IIC I2C level conversion module 5-3v system compatible Model: ICC I2C Power supply :5V-3V AVCC connect to 5V system power ASCL connect to 5V system SCL ASDA connect to 5V system SDA AGND connect to 5V system GND BVCC connect to 3V system power BSCL connect to 3V system SCL BSDA connect to 3V systems SDA BGND connect to 3V system GND 4 Channel If you've ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be. bi-directional logic level converter is a small device that safely steps down 5V signals to 3.3V AND steps up 3.3V to 5V at the same time. This level converter also works with 2.8V and 1.8V devices. What really separates this Logic level converter from our previous versions is that you can successfully 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. The level converter is very easy to use. 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.
