1-Channel 5V Relay Board for Arduino & Raspberry Pi
The 1-Channel 5V Relay Board lets an Arduino or Raspberry Pi control higher-voltage devices using a simple GPIO signal, acting like a safe electronic on/off switch for lights, fans, pumps, solenoids, and other loads. It takes a low-voltage control input from your microcontroller and toggles a mechanical relay, so you can isolate the control side from the load side while building automation projects. This module is ideal for smart home prototypes, timed switches, sensor-triggered power control, and DIY control panels where you need reliable switching from a 5V logic system.
