The Gravity: GP8501 2-Channel PWM to 0-2.5V/VCC DAC Module is an analog voltage output DAC module that features two channels and PWM communication. It boasts an 8-bit resolution and a precision of 0.5%. This module is particularly suitable for control projects that operate within a 3.3V range. It can be utilized with various microcontrollers such as ESP32, Raspberry Pi, and STM32, which necessitate analog signal output.

The module's design, which incorporates PWM signal drive, allows it to be controlled by MCU digital ports. This feature simplifies the usage and makes it more convenient. The inclusion of two channels in the design also contributes to a more cost-effective solution for projects.

The DAC series modules, to which this product belongs, can be controlled through I2C or PWM signals to generate voltage or current output signals. This series not only offers a wide range of output signal ranges but also provides three selectable resolutions: 8-bit, 12-bit, and 15-bit. The modules in this series allow for the selection of either single-channel or dual-channel configurations. Furthermore, multiple modules can be cascaded to form a multi-channel output.
