[chbot] stm32f103 "Blue Pill" boards

I've just discovered that the 10 new boards I got from AliExpress have a
clone CPU on them that I can't program (different ID - they are CS32F103
chips). Well actually I can program them but then debugging is tricky as
my toolchain doesn't support them.

Does anyone have one or two originals going spare as the last genuine one
I have appears to have a watchdog fault that causes a reboot every 25
seconds - a real pain to debug!
