I recently got my PICV3 Kit from this link and soldered everything up according to the RN2903 datasheet as well as this guide.
However very sadly it seems that the RN2903 chip is bricked beyond help as both the PICKit3 Utility as well as the MPLab X IPE could not connect to the board.
PICKitV3 utility:
MPLabXIPE:
Tried both LF45K50 and LF46K22 but to no avail.
Perhaps I will order the different model next time and design a PCB with proper ICSP breakout headers so I can eliminate the potential errors in soldering but I checked the connections with a multimeter several times and there was continuity…
Oh well for now I will just chuck this RN2903 aside in favour of a RAK3172…
Thanks regardless for all those who have helped me!
