- Brand NameEdiy
- TheoryVoltage Relay
- Feature 14 Channel Relay
- Feature 24 Channel Relay Module
- Feature 3.Raspberry Pi Relay Board
The weak current output by the Raspberry Pi IO can control the switching of strong currents through this product, and is often used in smart homes and other strong electric fields. Combined with the Raspberry Pi's network capabilities, remote control of home appliances can be achieved.
Note:The Raspberry Pi has 40Pin and 26Pin connectors. This product is only compatible with the 40Pin Raspberry Pi.
1.Suitable for Raspberry Pi A+/B+/2B/3B.
2.Using high quality relays.
3.Relay allows access up to 5A 250V AC or 5A 30V DC.
4.With optocoupler isolation, to avoid high-voltage circuit interference.
5.With relay indicator, easy to view the working status of the relay.
6.Jumper selection with relay for easy selection of other RSP control relays.
7.Comes with development means, including examples in wiringPi, WebioPi, shell, python, and bcm2835.
