## Description

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
