Black pill¶
Support for the stm32f103c8 based Black pill.
This board can be bought very cheaply on sides like eBay or AliExpress. Although the MCU nominally has 64 KiB ROM, most of them have 128 KiB ROM. This board is almost identical to the bluepill board, except for the pin layout and the on board LED is connected to PB12 instead of PC13.
