STM32F411 BlackPill Development Board
HighPerformance ARM CortexM4 Development Board
The BlackPill is a compact and affordable development board featuring the STM32F411CEU6 microcontroller. It offers significant performance improvements over the older "Blue Pill", including a faster core and more memory, making it ideal for complex embedded and IoT projects [citation:7].
HighPerformance CortexM4 100MHz ARM CortexM4 core with Floating Point Unit
Generous Memory - 512KB Flash and 128KB SRAM for demanding applications
Powered via USB Type-C or 3.3V pin, with a 3.3V 100mA LDO regulator on board.
Use the DFU bootloader via the USB Type-C port for programming; no external programmer is needed.
Note that the same GPIO pin can have multiple functions; check the datasheet for multiplexing details.
