Gravity: I2C 4-20mA DAC Module (Arduino Compatible)

This is an I2C DAC module that outputs 0–25mA current. It provides accurate 4–20mA current output after calibration, making it suitable for controlling industrial devices such as motors, inverters, valves, and pumps via Arduino or other microcontrollers.

Designed to convert digital signals into standard 4–20mA industrial control signals, this module serves as a bridge between microcontroller platforms and industrial systems.

With I2C communication and provided sample code, users can easily control the output current by setting digital values, enabling quick integration into automation and control projects.

This DAC module requires an external 18–24V power supply for proper 4–20mA loop operation.
