I’ll upload your files to the site. You could modify your rx/tx lines to/from the GPS to the 328 with solder pads that can be connected after configuration and flashing of the firmware. Another option would be to use a teensy board for development , which has more serial lines and would also be a viable option without the memory and processing limits of the 328. But perhaps the current code could be streamlined by a better coder for more efficient use of resources on the 328. Thanks for the upload, good luck!

Hi, I have made a pcb of the layout, check for errors, especially RX / TX lines.
I cant upload them in the filesection so I have put them here?? if an admin would like to upload them.
I have a similar pcb made for the qrp-labs u3s fw so I could probably make a working tracker with this ino file by cuttin two traces in the original pcb and solder in thin wires instead.
Can a test board with just the 328 and the 5351 soldered in without the GPS work, or does the code stop if there is no responce from the gps?
Toto on the pcb , make a couple of solder bridges so one can reprogram the board without lifting the gps.
