Description:

This voltage level shifter allows you to use modern 3.3v peripherals with older 5v microcontrollers.

 

Details:

- Plug the board into the center of your breadboard

- Wire the 3v3 pin (2) to one BB rail, the 5v pin (1) to another rail and the GND pin (3) to a common ground

- Pin 4 on the HIGH side connects to SDA from the 5v Uno or Nano, and pin 4 on the LOW side connects to SDA on the 3v3 peripheral

- Both I2C and four SPI connections are possible with this one board

- This is a voltage level shifter and can be used for any digital signal, not just I2C and SPI
