This is a 2-channel DAC module with I2C communication, a resolution of 15-bit, and an accuracy of 0.2%, capable of generating analog voltage outputs of 0-10V or 0-5V. The 0-10V or 0-5V voltage range is a standard driving method. It can be widely used in automation applications such as light adjustment, frequency converters, valve regulation, and pump control. This product can drive a variety of 0-10V or 0-5V controlled devices available in the market through Arduino programming. The high precision and resolution of this module make it suitable for control scenarios that require higher signal accuracy, such as fine speed control or angle control.
Features
- Support 3.3V-5V power supply.
- Output voltage error is less than 0.2%.
- Output voltage linearity error is 0.01%.
- Two channels of voltage output, either 0-5V or 0-10V, enabling connection and control of standard analog voltage devices.
- Gravity interface, I2C communication, Arduino control, suitable for program automation control.
