Description
The Gravity GP8101S 1-Channel DAC Module converts standard digital PWM signals from a microcontroller into an analog 0-5V or 0-10V output. Designed for makers, students, and automation engineers, it bridges low-voltage development boards with industrial-grade control hardware. It provides a simple and reliable method to drive equipment such as variable frequency drives, pumps, valves, and lighting controllers.
PWM to industrial analog conversion
Powered by the GP8101S chip, this module transforms digital PWM signals directly into standard 0-5V or 0-10V analog voltage. This enables standard microcontrollers to control industrial equipment without requiring complex external digital-to-analogue circuitry.
Seamless Arduino integration
Featuring a standard 3-pin Gravity interface, the board connects effortlessly to an Arduino UNO or compatible microcontrollers using digital I/O pins. The included Gravity cable provides a tidy, solderless connection for rapid prototyping.
Reliable 8-bit precision
The module offers 8-bit resolution, translating a 0-255 digital control range across your chosen voltage span. It maintains high accuracy with an output voltage error under 0.2% and a linearity error of just 0.1%.
Flexible supply voltage compatibility
Operating across a 3.3V to 5V supply range, the module interfaces smoothly with both modern 3.3V low-power boards and classic 5V microcontroller platforms.
Practical automation applications
The standard 0-5V and 0-10V output range makes this converter ideal for automatic lighting adjustments, variable frequency drive regulation, valve control, and automated water pump systems.
Package contents
Each pack includes one GP8101S 1-channel PWM to 0-5V/10V DAC module and one Gravity 3-pin analog sensor cable.
