Relay module to db9 wiring

[Rob F]

No problem, glad you got it. I think your board has the solder pad but it might not, here's where it would be.



If you don't have it you can solder a wire from the +5v or +12v points I marked out to the DB9 housing.

2nd power bar would be easier but I have some if you need.

Thanks for the help Rob. I order my second one today...

Thanks, I appreciate it! I'll get it out on Monday and email you a tracking number.
