This is a relay expansion board specially designed for Raspberry Pi with 3 or 8 relays control.
Generally, the Raspberry Pi is used in the field of weak electricity.
Using this product can make the Raspberry Pi enter the strong electricity field such as smart home.
Through its connection, the Raspberry Pi can control home appliance devices easily.
1. Based on Raspberry Pi 40pin GPIO interface, suitable for Raspberry Pi series motherboards
2. Adopt high-quality relays and allow load connection: ≤5A 250V AC or ≤5A 30V DC
3. With optocoupler isolation to avoid high-voltage circuit interference
4. With relay indicator, easy to check the working status of the relay
5. With relay selection jumper cap, it is convenient to switch other pins of Raspberry Pi for control
1. Raspberry Pi GPIO interface :
Easy access to Raspberry Pi
2. Relay terminal :
Convenient for external control lines
4. Optocoupler : PC817 optocoupler chip
5. Relay working indicator :
LED is on, normally closed end of relay is open, normally open end is closed
LED is off, normally closed end of relay is closed, normally open end is disconnected
6. Power Indicator
7. Relay control pin selection jumper :
Jumpers Connecting: Connecting to the I / O specified by the sample program
Disconnect the jumpers: you can use the connection cable to access the custom I / O
