The I2C Level Converter allows you the run 3.3V logic sensors like the Bar30 or Celsius and other accessories off of a 5V logic device like the Arduino Uno!
A selectable solder jumper lets you run 5V or 3.3V power to your sensor, independent of the 3.3V I2C logic. Built in four-pin DF13, JST GH, and 0.1″ header pin connectors provide maximum flexibility and ease of use.

1. Determine if your device is 3.3V or 5V powered and set solder jumper for correct output. Many I2C devices are 3.3V, but the Bar, BarXT, and Celsius sensors operate best with 5V power.
2. Plug your device into one of the ports (4 pin 0.1” header, JST GH, DF13) on the 3.3V side.
3. Connect your 5V host device to the pins on the 5V side. Make sure the level converter is powered with 5V on the +5V pin.
4. That’s it! You’re ready to communicate between the devices.
