Wrote up my "learning experience" ordering the wrong MCU board to install Black Magic Probe onto, and how I installed it.

(For the newbie to embedded programming - in which category I include myself - Black Magic Probe is a very neat bit of software that connects GDB to devices ARM Cortex CPUs so you can single-step your embedded code)

take home: "black pill" is, aside from being an unfortunate name for - well, basically anything, a bad choice of name to use for two different boards based on two different MCUs
