I have a pile of Blue Pill boards, and using it to read floppies was an
obvious application. However after running the numbers, it turned out there
isn't enough RAM to buffer an entire track from a HD floppy. It also has a
broken USB implementation just to liven things up a bit.

The Raspberry Pi Pico has a similar price to the Blue Pill and seems a much
better machine for this task, although I haven't combed through its
reference manual yet.
