  • Maybe later, I sacrifice one in the name of science :-)

    Yes, definitely optional thing for later.

    As for sacrifices - it should be possible to restore it either over BLE or at worst it should be always recoverable via SWS interface - pin on board. This is similar debugging/programming interface to ARM SWD but thanks to clever hack you even don't need special HW for recovery, the right data for SWS can be generated in software and sent via serial uart.

    Anyway, they are pretty cheap after all (below $4/piece when getting 4 of them­35569.html ) so even if completely broken it is not that bad :-)
