Pin layout and GPS wiring diagram.

Apparently my son's radio still thinks it's Christmas

My daughter and I successfully sent and received test texts to one another once everything was setup.

If you are going to use a GPS with your unit you will need to enable the GPS mode and then set the rx and tx pins that you have soldered to on the circuit board of the radio. Here they're set to 48 and 47, respectively.

I filed it down! I'm not an electronics guru so it took me a bit to realize that I just need to manipulate the environment in which the Heltec V3 is going to occupy inside the radio frame. I'm considering using hot glue to help secure the radio in place now that the shelf/lip is gone. We'll see once it's in place, but in the meantime, I need to get a replacement radio.

The radio frames made by Tony G on printables.com truly are well designed and if anyone is thinking about building meshtastic radios I would highly suggest downloading any of his designs that suits your needs.

I would have only one fix for this radio frame though, it's this blasted lip/shelf where the heltec v3 is supposed to sit. The design prohibits the connections for the hot and ground wires to the GNSS radio to sit. Granted, I'm not good at soldering but I was good enough to ruin my radio trying to find a way to get the wires soldered in a way that would work. But I think I have a solution.

Ruined one of my Heltec V3's by soldering and resoldering the connections for the hot and ground wires trying to get it to fit into the radio frame.

It has me pinpointed
