G1

[mcdave]

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.
