8 Channel I2C IIC Logic Level Converter Module Bi-Directional for Arduino

Description: The level converter is very easy to use. 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 Compatible with 5-3V system VIN connected 5V system power supply 5A connected 5V system 5B connected 5V system GND connected 5V system GND 3V3 connected 3V system power supply 3A connected 3V system 3B connected 3V system GND connected 3V system GND Size: 28 x 19mm / 1.1 x 0.74 inch Package Included:10pcs x 8 Channel IIC I2C Logic Level Converter Module
