Gravity: GP8211 I2C 15-bit DAC Module (0-5V/10V)

This is a 1-channel DAC module with I2C communication, a resolution of 15-bit, and an accuracy of 0.01%, capable of generating analog voltage outputs of 0-10V or 0-5V. The 0-10V or 0-5V voltage output is a standard driving method. It can be widely used in automation control scenarios such as lighting adjustment, frequency converters, valve regulation, and pump control,etc. 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.

DAC series modules are a range of products that can be controlled through I2C or PWM signals to generate voltage or current output signals. This series of DAC products not only offers a variety of output signal ranges, but also provides three selectable resolutions: 8-bit, 12-bit, and 15-bit. It allows for the choice of either single-channel or dual-channel configurations, and multiple modules can be cascaded to form a multi-channel output.
