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.
