Black Pill

Modernized with a USB-C connector and a more stable internal oscillator.

Good to know

USB DFU bootloader from the factory: hold BOOT0 + reset, then flash over USB-C.
4-pin SWD header at the end – debugging is comfier with an ST-LINK.
The PC13 LED is wired as a sink: LOW = lit.
Many pins are 5V tolerant (FT), but the analog inputs are not.
