DISCONTINUED - Product listed as reference only, we still sell the kits that you solder yourself as these are extremely popular

The fully built and tested version of our very popular kit.  For the kit see https://store-8d73a.mybigcommerce.com/kit-relay-board-simple-to-use-5v-operation-supports-logic-level-also-10amp/

Many people asked if we did a "normal" style relay, a version that required just a single input to turn on/off.

So we designed this.

You need 5v to power the relay coil (4v to 6v 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.

Current stock uses IMO relays (as pictured), we also use Shrack, Omron and others that are compatible.
