Perfect for simple home-automation projects, this module allows your Raspberry Pi to control three independent relays, allowing you to easily control high-current loads while keeping your Pi safely isolated. All the necessary driver circuitry is on-board, and control is as simple as driving a GPIO pin high or low. Relays can be easily disconnected from their corresponding GPIO by removing an on-board jumper, allowing you to free-up unused channels for other purposes. Standoffs are included to help secure the module to your Pi.
To get you started, we have a simple python script that you can download (must have internet connection):
curl -L http://coreelec.io/34 >> relay-test.py
Then run it with
python relay-test.py
You should see the relays sequence on then off.
Note: This is compatible with all Pi 3 and 4 model B/B+ boards.
