A "normal" style relay to switch a single "data" line to turn on/off.   Perfect for RaspberryPi or Aduino projects. You need 5v to power the relay coil. The input (IN) requires just a few milliamps at anywhere between 2.5v and 12v. You can even use the same voltage you are powering the coil from. Features: ·         Low cost way to control larger voltages and currents. ·         No soldering required ·         Supports any micro-controller  ·         On-board switching transistor. ·         Easy 1 wire drive. High for on, low for off.  ·         Mains rated relay. Pinouts (from the left)  5v supply (coil requires 400mw) GND IN data line (TTL 3-12v) A1 - contact 1 (normally open, applies to all models) A2 - contact 2 (normally closed, only on 6 pin relays). COM - common Raspberry PI Relay switch example which will switch the relay on and off at 1 second intervals: Wiring: Connect VCC to Rpi Pin 2 (5V) Connect GND to Rpi Pin 6 (GND) Connect IN to Rpi Pin 7  Connect the Ground of the c
