A 1-channel DAC module that converts a PWM signal from any microcontroller into a precise 0–5V or 0–10V analogue voltage output. Built around the GP8101S chip with 8-bit resolution and 0.2% accuracy, it's ideal for driving standard 0–10V or 0–5V controlled devices in automation projects — lights, frequency converters, valves, pumps, and more.
Controlled via PWM from a digital MCU pin through the Gravity 3-pin interface, making it simple to integrate with Arduino and other development boards. Compatible with both 3.3V and 5V systems.

Jargon buster
Plain-language definitions for the technical terms used above.
- DAC
- A digital-to-analogue converter turns numbers from the microcontroller into a real analogue voltage. It matters if you want to generate simple waveforms, audio-style signals, or variable control voltages rather than just on/off outputs.
- ESP32
- ESP32 is a family of microcontroller modules with built-in wireless features such as Bluetooth and WiFi. Knowing this product uses an ESP32-based module helps explain how it provides wireless serial communication and firmware update features.
- Gravity
- Gravity is DFRobot’s plug-in connector system for sensors, motors and modules, using standard cables to reduce loose jumper wiring. It matters because Gravity-compatible parts can connect directly to these ports, while non-Gravity parts may need adapters or manual wiring.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
