The STM32F401 Black Pill Development Board is a powerful and compact ARM Cortex-M4 based board designed for advanced embedded system development. Featuring the STM32F401CCU6 microcontroller, it comes with a 32-bit ARM Cortex-M4 core running at up to 84 MHz, 256 KB Flash memory (ROM), and 64 KB SRAM, making it suitable for complex applications that demand performance and efficiency.
This development board includes USB connectivity, multiple GPIO pins, I²C, SPI, UART, ADC, DAC, and PWM outputs, providing versatile interfacing for a wide range of projects. It operates at 3.3V logic but is also tolerant to 5V input, allowing compatibility with many sensors and peripherals. Its compact “Black Pill” form factor ensures easy integration into breadboards, prototyping setups, and custom PCB projects.
The STM32F401 Black Pill is widely supported by popular IDEs such as STM32CubeIDE, Keil uVision, and Arduino IDE (via STM32duino), making it beginner-friendly yet powerful enough for professionals. It is ideal for applications such as IoT devices, robotics, motor control, real-time data processing, signal acquisition, and machine learning on edge devices.
With high-speed processing, low power consumption, and rich peripheral support, this development board is a great alternative to Arduino, offering significantly more performance for demanding projects.
