4 Channels IIC I2C Logic Level Converter Bi-Directional Module 3.3V to 5V Shifter for Arduino Product description： Color: Blue Material: Glass fiber How to use it: The level converter is very easy to use, it needs to be powered from the two voltages sources (high voltage and low voltage) that your system is using. Take the high voltage (5V) and low voltage (3.3V) for example. 5V connects to HV pin; 3.3V connects to LV pin; Ground from the system connects to GND pin. Four MOS transistors achieve bidirectional conversion of four 3V and 5V levels The power input is equipped with anti reverse protection, integrated with 3.3V LDO, and can provide a current of no more than 150mA to the outside world Equipped with a power indicator light, it is easy to see whether it is working or not Can achieve bus signals such as UART, IIC, 1-wire, SPI at 3V-5V levels Attention: This product is a level conversion module, not a power conversion module!! It must be connected to a 5V power supply to function properly!
