4-Channel 5V Relay Module for Arduino & Raspberry Pi
The 4-Channel 5V Relay Module lets an Arduino or Raspberry Pi control up to four devices independently, acting like four GPIO-controlled on/off switches in one board. It is a great middle ground when you need more than a single relay but do not want a large multi-relay panel. Use it for multi-zone lighting, pumps, fans, solenoids, small automation panels, and test setups where you want simple, reliable switching from a 5V control system.
