This 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. It also works with 2.8V and 1.8V devices. 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 four pins on the high side to four pins on the low side with two inputs and two outputs provided for each side.
Using this level converter is easy. The board needs to be powered from the two voltage sources that your system is using (make sure you use regulated supplies). The higher voltage (e.g. 5V) goes to the HV pin; the lower voltage (e.g. 3.3V) goes to the LV pin; ground from the system goes to the GND pin.
