4 Channel Bi-Directional Logic Level 3.3V-5V Shifter

4 Channel Bi-Directional Logic Level 3.3V-5V Shifter

The module performs bi-directionally transfer with 4 channels between high logic voltage and low logic voltage. That is, steps down 5V signals to 3.3V and steps up 3.3V to 5V at the same time.

Each logic level converter has the capability of converting 6 pins on the high side to 6 pins on the low side with two inputs and two outputs provided for each side. Wiring Pinouts:

  1. 5V connects to HV pin
  2. 3.3V connects to LV pin;
  3. Ground from the system connects to GND pin.
