## Description

##Introduction This is a 2-channel analog voltage output DAC module with I2C communication, 12-bit resolution, and 0.1% 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.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: GP8503 2-Channel 12bit I2C to 0-2.5V/VCC DAC ModuleWiring Diagram of Gravity: GP8503 2-Channel 12bit I2C to 0-2.5V/VCC DAC Module and Arduino UNOWe provide various models of DAC modules.
