Gravity: GP8501 2-Channel PWM to 0-2.5V/VCC DAC Module

SKU: DFR1037

This is a 2-channel DAC module driven by PWM signals, with 8-bit resolution and 0.5% precision, featuring analog voltage output of 0-VCC or 0-2.5V for each channel. It is ideally suited for control projects with a voltage of 3.3V or below, and perfect for analog signal output by mainstream main controllers such as ESP32, Raspberry Pi and STM32. Powered by PWM signals, this module can be directly driven via the digital ports of an MCU, enabling simple and convenient operation. Its 2-channel design also effectively reduces the overall project cost.
