Please note: Raspberry Pi not included
The RPi Relay Board gives your Pi the ability to control high voltage/high current devices, easily makes normal home appliances become intelligent.
RPi Relay Board Features
- High quality relays, loads up to 250VAC/5A, 30VDC/5A
 - Photo coupling isolation, prevent interference from high voltage circuit
 - Onboard LEDs for indicating relays status
 - Relay control jumper, allows to control the relays by custom pins other than the default pins
 - Comes with development resources, including examples in wiringPi, WebioPi, shell, python, and bcm2835
 

What's on the RPi Relay Board

 - Relay screw terminal: for connecting target devices
 - Relays
 - Photocoupler: PC817
 - Relay indicator
 - LED on: relay NC is opened, NO is closed
 - LED off: relay NC is closed, NO is opened
 - Power indicator
 - Relay control jumper
 - short the jumper: control the relays by default I/Os used in the example code
 - open the jumper: control the relays by custom I/Os through jumper wires
