## Description

This is a 1-channel DAC module with PWM communication, a resolution of 8-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 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.

PWM signal drive allows the module to be controlled by MCU digital ports, providing a simple and convenient usage.

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.
