Product details

Overview

The STM32F401CCU6 Black Pill is a powerful, versatile development board that bridges the gap between hobbyist microcontrollers and industrial-grade embedded systems. Unlike the older F103 series, the F401 "Black Pill" includes a Floating Point Unit (FPU) and more robust power management, making it perfect for signal processing, motor control, and AI-on-the-edge experiments.

With its USB Type-C connector, you no longer need to worry about fragile Micro-USB ports. It is fully compatible with the STM32Cube ecosystem, Keil, IAR, and can also be programmed via the Arduino IDE using the STM32duino core.

Why Choose the Black Pill?

  1. The FPU Advantage: Perform complex mathematical calculations (like PID loops or FFTs) significantly faster than standard Cortex-M3 or AVR chips.
  2. USB-C Reliability: Built for longevity with a modern, reversible USB-C port.
  3. Storage: 256KB of Flash allows you to run modern RTOS (Real-Time Operating Systems) like FreeRTOS or Zephyr with ease.
  4. On-board Button: Includes a user button (PC13) and a reset button for quick testing.

Programming Note: To flash this board, you can use an ST-Link V2 Debugger or use the built-in USB DFU bootloader by holding the 'Boot0' button during power-up.
