Description
Specifications

This is a 2-channel analog voltage output DAC module with PWM communication, 8-bit resolution, and 0.5% precision. It is well-suited for control projects operating within the 3.3V range, such as ESP32, Raspberry Pi, STM32, and other microcontrollers that require analog signal output. PWM signal drive allows the module to be controlled by MCU digital ports, providing a simple and convenient usage. The design with two channels also enables effective cost reduction for the project.

Features

Support 3.3-V-5V power supply.
Output voltage error is less than 0.5%.
Output voltage linearity error is 0.1%.
Two channels of voltage output, either 0-2.5V or 0-VCC, enabling connection and control of standard analog voltage devices.
Gravity interface, PWM communication, Arduino control, suitable for program automation control.
PWM signals can be utilized to drive the module, enabling it to be controlled simply by the digital port of the MCU.

Applications

Motor speed control
Sound volume control
Indoor and outdoor lighting brightness adjustment
Display screen backlight automatic adjustment
