DFRobot Gravity GP8403 2-Channel I2C DAC Module (0-10V)

The Gravity 2-Channel I2C DAC Module (0-10V) is a versatile digital-to-analog converter that allows your microcontroller to generate precise analog voltage signals.

This module features two independent output channels, each capable of producing voltage from 0V to 10V with 12-bit resolution (4096 levels), making it ideal for controlling analog devices, industrial equipment, or simulating sensor outputs.

The simple I2C communication interface makes it compatible with Arduino, Raspberry Pi, micro:bit, and other popular development boards, requiring just two pins for communication plus power connections.

Designed with practicality in mind, this DAC module includes convenient screw terminals for secure wiring, a power indicator LED, and a compact form factor that fits easily into your projects. The module operates on 7-12V DC power supply and provides stable output even in noisy environments.

Whether you’re building industrial automation systems, controlling motor speed, adjusting LED brightness, or creating test equipment, this DAC module offers the precision and reliability you need.

The included sample code and libraries make it easy for students and hobbyists to get started quickly, while the robust design ensures it can handle demanding applications in educational labs or small businesses.
