GPIO pin mapping - yehuda80 - 2016 Apr 14
Hi Everyone
I just got the SIP server up and running on a brand new PI 3 connected to a board with 8 relays
I have to say this project is really great. made my life really easy.
i managed to login to the website and tried to manually enable stations but i can't figure out the GPIO pin mapping
how can i tell what GPIO pin controls what station. ?
Thanks a lot
Yehuda

Hi Yehuda,
Do you have the relay_board plugin installed? If not go to the Plugins menu and under Manage Plugins select Browse More Plugins then select and install the relay_board plugin.
You can find the pin configuration here:

Hi Dan
i installed the relay plugin and it worked well.
BTW - i found this PI 3 schmatics that shows the GPIO pins connection to the 40-pin header.
for some reason it shows two different numberings for the SOC GPIO lines
i think the one that is relevant is the one in brackets (with the GEN suffix)
but that one only shows 8 GPIO available
Do you know how to read this GPIO mapping correctly ?
Thanks !

Was there supposed to be a link in your last message?
I'm not sure where to find the schematics you are referring to.

I'm not sure what the GEN numbers are.
This site may have the information you need.

Click a pin on the diagram for detailed information of what each one does.
