Raspberry Pi Relay Board

The Raspberry Pi Relay Board gives your Raspberry Pi the ability to control high voltage devices, it can be used to control normal home appliances and make a smart digital house.

Raspberry Pi Relay Board Features

• Supports Raspberry Pi A+/B+/2B/3B
• 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
