'''Documentation notice:''' This technical documentation was independently rewritten from an archived supplier source. Check technical details and commands against the product version and manufacturer documentation before use.<br />
<br />
== Summary ==<br />
The RPi Relay Board is a Raspberry Pi expansion board with three relay channels driven via GPIO pins. It allows switching external loads through NC/NO contacts and provides demos in shell, C (bcm2835/wiringPi), Python, and web-based control.<br />
<br />
== Related products at JW Tech ==<br />
* [https://shop.jw-tech.eu/p/WSAL11638 WSAL11638 – RPi Relay Board]<br />
<br />
== Technical overview ==<br />
* Three relay channels (CH1–CH3) map to RPi pins P25 (BCM 26), P28 (BCM 20), and P29 (BCM 21).<br />
* The Relay_JMP jumper must be installed for the Raspberry Pi to control the relays.<br />
* Relays are low-level triggered: a Low output lights the corresponding LED, closes the NO contact, and opens the NC contact.<br />
* Each channel has a screw terminal block with three pins for connecting external circuits.<br />
* When cabled instead of stacked on the pin header, connect 5V, 3.3V, and GND for power.<br />
* Multiple boards cannot be stacked due to relay height; they can be daisy-chained with Dupont cables.<br />
* The demo package includes shell, C (bcm2835/wiringPi), Python, and web-control scripts accessible on port 8080.<br />
* If the control signal appears inverted or no response occurs at high level, it is because the relay activates on a low signal.<br />
<br />
'''Commands and examples – verify before use:''' <br />
<syntaxhighlight lang="text"><br />
sudo ./Relay.sh CH1 ON<br />
sudo ./Relay.sh CH2 ON<br />
sudo ./Relay.sh CH3 OFF<br />
make<br />
sudo ./Relay_Module<br />
sudo python Relay_Module.py<br />
python3 main.py<br />
</syntaxhighlight><br />
<br />
== Notes and version constraints ==<br />
* Library versions (e.g., wiringPi 2.52 vs. 2.70) depend on the OS version; verify before installing.<br />
* Web control requires Google Chrome; other browsers may be incompatible.<br />
* After running the Python demo on VisionFive2, pins may become unresponsive — restart or run clear.sh.<br />
* Specific voltage values, certifications, or warranty details are not provided in the source; do not invent them.<br />
