DFROBOT DFR1034 I2C to DAC Module, GP8503, 2Channel, 0 to 2.5V/VCC, DFRduino UNO v3.0 Boards

DFR1034 is a gravity: GP8503 2-channel 12bit I2C to 0-2.5V/VCC DAC module. This is a 2-channel analogue 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 analogue 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: 8bit, 12bit, and 15bit. 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. Typical applications include motor rotational speed regulation, sonorous intensity modulation, indoor and outdoor luminance modulation, display panel backlight automatic adjustment.
