STM32F401RCT6 – STM32 Development Board – The Black Pill The STM32F401 Black Pill Development Board is an enhanced version of the popular Blue Pill, which is based on the F103. This newer model has a more powerful Core-M4F-based ARM CPU. The DFU bootloader is supported by both the F401 and F411 processors. The Cortex®-M4 core includes a single-precision floating point unit (FPU) that supports all Arm single-precision data-processing instructions and data types. It also includes a complete set of DSP instructions and a memory protection unit (MPU) to improve application security. The STM32F401 includes high-speed embedded memories as well as a wide range of enhanced I/O and peripherals that are connected to two APB buses, two AHB buses, and a 32-bit multi-AHB bus matrix. The STM32F401 incorporates high-speed embedded memories (up to 256 Kbytes of Flash memory, up to 64kB of SRAM), and a wide range of enhanced I/Os and peripherals connected to two APB buses, two AHB buses and a 32-bit multi-AHB bus matrix. Features: Based on an ARM Cortex-M4 core with hardware floating-point unit (FPU) and DSP instructions. Breadboard-friendly dual 20-pin (2.54 mm) header layout for prototyping and easy wiring. USB-C (or USB type connector) interface for board power and programming. Boot0 and Reset buttons (and often a User key) integrated for firmware upload and boot-mode control. All I/O pins broken out and many are 5 V tolerant (depending on variant). On-board power regulation (e.g., 5 V to 3.3 V) enabling safe use from USB or external power.
