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.The high precision and resolution of this module make it suitable for control scenarios that require higher signal accuracy, such as fine speed control or angle control.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: GP8512: 1-Channel 15bit I2C to 0-2.5V/VCC DAC ModuleWiring Diagram of Gravity: GP8512: 1-Channel 15bit I2C to 0-2.5V/VCC DAC Module and Arduino UNOWe provide various models of DAC modules.
