Description
The Raspberry Pi Relay Board gives your Pi the ability to control high voltage/high current devices, easily making normal home appliances become intelligent.
Features
- Standard Raspberry Pi 40PIN GPIO extension header
- Supports Raspberry Pi 2/3/4
- 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 you 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 Board
