Gravity: I2C 4-20mA DAC Module (Arduino Compatible)
The Gravity I2C 4-20mA DAC Module outputs 0–25 mA of current controlled via I2C, with high-accuracy 4–20 mA output available after calibration (0.2% linearity error). Built around the GP8302 chip, it provides 12-bit resolution and is compatible with Arduino, enabling precise current-loop control of industrial devices such as motors, inverters, valves, and pumps.
The module uses a Gravity I2C interface for easy connection and requires an 18–24V power supply (24V recommended). It supports a maximum load resistance of 750Ω at 24V, with a start-up time under 2 ms and operating temperatures from −40°C to 125°C.
