The Logic Level Converter Module provides a bidirectional interface between devices operating at different voltages. The typical application is use of 3.3V sensors or devices with a 5V microcontroller such as an Arduino. Up to 4 digital I/O lines can be converted.The board needs to be powered from the two voltages sources (high voltage and low voltage) that the 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.
