Retired Product

This product has been retired and kept here for reference.

Many people asked if we did a "normal" style relay, a version that required just a single "data" line to turn on/off.  So we designed this.

You need 3v to power the relay coil (2.8v to 4v will do). The input (IN) requires just a few milliamps at anywhere between 2.5v and 12v. You can even use the same volatge you are powering the coil from.

  • Low cost way to control larger voltages and currents.
  • Relay supplied will vary depending on stock; will either be a 7A or 10A device.
  • Supplied as a kit. Easy to build.
  • Supports any microcontroller or TTL signal (3.3ma drive max) 3.3v to 5v supported. Relay current consumption at 5v is 73ma (on the IMO relay pictured)
  • On-board switching transistor.
  • On-board back EMF protection.
  • Easy 1 wire drive. High for on, low for off.
  • Small size 50mm long x 26mm wide x 19mm high
  • mains rated relay

  1. Review by Nickname - Perfect for PI verified purchaser

    Great little board easy to assemble and easy to use, works flawlessly with the Raspberry Pi.

    Loses one star as it is only rated to 7A at 240VAC, which is different to the picture. (Posted on 29/11/2014)
