Description Features Datasheet

The RPi Relay Board gives your Pi the ability to control high voltage/high current devices, easily makes normal home appliances become intelligent.

What's on the RPi Relay Board

  1. Raspberry Pi GPIO interface:for connecting Raspberry Pi
  2. Relay screw terminal:for connecting target devices
  3. Relays
  4. Photocoupler:PC817
  5. Relay indicator
    • LED on: relay NC is opened, NO is closed
    • LED off: relay NC is closed, NO is opened
  6. Power indicator
  7. Relay control jumper
    • short the jumper: control the relays by default I/Os used in the example code
    • open the jumper: control the relays by custom I/Os through jumper wires
