Pico Relay Board

Raspberry Pi Pico Relay Board is developed by SB Components with the potential to control up to 4 appliances and loads up to 250V AC@ 7A, 30V DC@ 10A. It provides a way for the users to control the high voltage/current devices.


  • 4 High-quality Relay and loads up to 250V AC@ 7A, 30V DC@ 10A.
  • Optocoupler (CTR: 50~600% at IF =5mA, VCE =5V)
  • Indication LED’s for Relay output status.
  • Relay control jumpers allow the user to control the relays by custom pins other than the default pins.
  • 40-Pin Stacking Header for Pico.
  • 40 Pin External Male Headers for GPIO
