Digital-to-analog converter equipped with a Gravity series connector. It has two channels - one with a current output in the range of 0 mA to 25 mA, and the other for connecting the power supply in the range of 18 V to 24 V DC. The DAC is compatible with Arduino, so it can be used with a wide range of peripherals such as light controllers, inverters, valves and pumps. The maximum resistance for an 18 V supply is 450 Ohm and for 24 V up to 750 Ohm.
Main features:
- Equipped with GP8403 chip
- It has a stable output current with a slight error of up to 0.2% after calibration
- Wide supply voltage range from 18 V to 24 V DC
- It has a Gravity connector and uses the I2C bus for communication
- Current consumption is less than 5 mA
