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.
