4 Channel Logic Level Converter

Specifications:

• Safely steps down 5V signals to 3.3V and steps up 3.3V to 5V at the same time
• Converter also works with 2.8V and 1.8V devices
• 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.
