[chbot] STM32F103RET6 board

[Robin Gilks]

Your lucky day

I had a bag of Blue Pills arrive only 3 days ago :)

I'll try and remember to bring one tomorrow evening. Do you need a
programmer/debugger as well? (they don't come with a USB bootloader like
some/most Arduino do and the serial bootloader is a pain!).
