QX7 ACCESS board, any extra inputs available for switches or POTs?

Post by Speedy »

The QX7 ACCESS board appears to be fairly different from the ACCST version. For one, it doesn't have the extra connectors. See picture below.

In considering adding the extra switches and pots, erskyTx appears to support several inputs:

Switch PB1/2 = JTMS, JTCK, EXT 1, and EXT 2
Pot 3/4 = PC5, PB1

Are PC5, PB1, JTMS and JTCK the respective pins on the STM32 chip? What are EXT 1 and 2? Are these unused pins or have they been re-purposed?
