Relay Control PCB
A bare PCB for building a relay control circuit, based on SparkFun's Controllable Power Outlet tutorial. It allows you to switch high-voltage loads using a simple 0–5V GPIO signal from any microcontroller. Components must be sourced and soldered separately.
Key Features
- Bare PCB – Solder your own components for a custom relay controller
- GPIO Controlled – Switch with a 0–5V signal from any microcontroller
- High-Voltage Switching – Control mains-powered devices safely
Ideal For
- Microcontroller-switched power outlets
- Home automation relay circuits
- Learning relay control electronics
Package Contents
- 1× Relay control PCB (bare board, components not included)
