This is DFRobot Gravity: I2C 4-20mA DAC Module (Arduino Compatible).

This is an I2C DAC module that outputs 0-25mA current. It offers more accurate 4-20mA current output after calibration, which can be used with most 4-20mA devices on market such as motors, inverters, valves, pumps, etc., by Arduino programming.

  1. Intelligent function signal generator.
  2. Automatic controller for lighting or fountain.
  3. The automatic and quick transformation of small equipment.
  4. Automatic debugger for electromechanical equipment.
  5. Transformation of small test equipment.


  1. I2C signal input, linearly converted to 0-25mA analog current output.
  2. With Gravity interface, support the Arduino library, and can be used for program automation control.
  3. Configuration can be saved when powered off, and the saved value remains after restarting.
