DFR1037

DFR1037 is a Gravity: GP8501 2-channel PWM 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. 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, 12 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 speed control, sound volume control, indoor and outdoor lighting brightness adjustment.

• Support 3.3V-5V power supply
• Output voltage error is less than 0.5%
• Output voltage linearity error is 0.1%
• 2ch 'V' O/P, either 0-2.5V or 0-VCC, enabling connection, control of std analogue voltage devices
• Gravity interface, PWM communication, Arduino control, suitable for program automation control
• PWM signals can be utilized to drive mod, enabling it to be controlled simply by digital port of MCU
