Gravity: 1 Channel 15-Bit I2C to 0-2.5V DAC Module, GP8512 - 

DFR1035 is a Gravity: GP8512: 1-channel 15bit I2C to 0-2.5V/VCC DAC module. It is well-suited for control projects operating within the 3.3V range, such as ESP32, Raspberry Pi, STM32, and other MCUs that require analogue 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 3 selectable resolutions: 8, 12, 15bit. It allows for choice of either 1ch or 2ch configurations and multiple modules can be cascaded to form a multi-channel output. Typical applications include orchestrates automatic control of motor rotational speed, facilitates automatic modulation of volume, governs temperature through automatic control mechanisms.
