This moduleis a 4-Chanel 5V-3V logic convertor that convert the 5V logic communication to 3V and vice versa. It is the bridge of communication between 3V logic device and 5V logic device. For example, if the Uno communicate with your sensor via I2C protocal, but your Arduino Uno is working in 5V logic while you sensor works in 3.3V logic, you can use this convertor to make the communication stable.
Four MOSFET to realize four road 3 v and 5 v Logic Converte
Power input protection meter, integration 3.3V LDO, and can provide no more than current of 150 mA
With power LED, indicate work or not
It can realize UART, IIC,one- wire, SPI bus signals such as 3 v to 5 v level of two-way transformation
