Gravity I2C 2-Channel DAC Module 0-10V

The Gravity module from DFRobot with the GP8403 converts values via I2C into two analog voltages of 0 to 10 V or 0 to 5 V. This lets an Arduino or ESP32 control devices with an analog input, for example dimmers for LED lights, frequency inverters, valves or pumps. Eight addresses can be set with a DIP switch, so eight modules with a total of 16 outputs run on the same bus.

With 15 bit there is the Gravity GP8413 2-Channel I2C to 0-5V/10V DAC Module.

Note: The connection cable can be converted to male pins with a Dupont cable M-M, so that it also fits an Arduino UNO.
