RPi Relay Board Features

• Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards
• High quality relays, loads up to 5A 250V AC or 5A 30V DC
• 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

• 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
