Waveshare 3 Channel Relay HAT Smart Home for Raspberry Pi 3

Create your DIY 3 channel remote control to ON-OFF three electrical devices from your Mobile application.The Waveshare 3 Channel Relay HAT Smart Home for Raspberry Pi 3 gives your Pi the ability to control high voltage/high current devices, which can be operated up to 230V AC 5A current easily makes normal home appliances become intelligent.

What’s on the RPi Relay Board:

• Raspberry Pi GPIO interface: for connecting Raspberry Pi
• 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 with custom I/Os through jumper wires

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
