Overview

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

• 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

1. Raspberry Pi GPIO interface: for connecting Raspberry Pi
2. Relay screw terminal: for connecting target devices
3. Relays
4. Photocoupler: PC817
5. Relay indicator

• LED on: relay NC is opened, NO is closed
• LED off: relay NC is closed, NO is opened

• 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
