- The backup record's fallback RX pin is 35, as the radio's default is. - BootPins.h, pins.js and Transceiver.cpp say to keep the pins, the radio pins checked and the shared RX/TX rule in step. - index.js reads the chip model through one chipModel(). - BootPins.RADIO is RADIO_PINS; the P4 test builds its config once.
