If you've ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be. The 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. Small size, 4.1× 1.8cm/ 1.6× 0.7in
Take the high voltage (5V) and low voltage (3,3V) for example.
5V connects to HV pin;
3.3V connects to LV pin;
Negative pole connects to GND pin.
