G1 - mcdave - 02-10-2026
Hi Admin,
I am planning to add a relay module to the G1, and I was wondering if you have any diagrams that I could use as a reference for how to properly add it.
This correct?
GPIO12 → relay IN
GND → relay GND
5V → relay VCC
12V+ → COM
NO → Siren+
Siren- → GND
Thank you for your help.

G1 free GPIO can't driver relay coin directly, it's no driver. not enough current.

Please confirm if I should use the relay module for this setup and verify that 12V is required to power the device on the relay side.
Control side:
GPIO → IN
GND → GND
5V → VCC
Power side:
12V+ → COM
NO → Siren+
Siren– → GND
This Correct?

can you draw on paper, so that easy to understand.
