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

##Introduction 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.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.Functional Diagram of Gravity: GP8501 2-Channel PWM to 0-2.5V/VCC DAC ModuleWiring Diagram of Gravity: GP8501 2-Channel PWM to 0-2.5V/VCC DAC Module and Arduino UNOWe provide various models of DAC modules.
