The Black Pill development board is a good choice. Of the commercially available development modules, this is one of the best. It was designed by WeAct Studio, but like the Blue Pill many different versions exist. Unlike the Blue Pill, at least at the time of writing this, they all appear to be using genuine STM32 processors (read: no cheaper clones exist). Here are two different ones, both of which I suspect are clones (and both working just fine):
The Black Pills are typically based on a STM32F401 or STM32F411 (both of the above are the F411 version) and offers the following specs:
- STM32F4 (STM32F401 or STM32F411) processor
- Same footprint (I/O pins)
- 25 MHz main crystal
- 32.768 kHz RTC crystal
- USB-C connector
- Programming header
EEPROM Footprint
The Black Pill board usually have an unpopulated footprint on the reverse side of the PCB intended for a generic EEPROM:
On the Board Info page, this is documented as:
Unfortunately, the clone Black Pill boards are wired up different.
