STM32F401CCU6 V3.0 Development Board (Black Pill)

Meet the “Black Pill”upgraded. The STM32F401CCU6 Development Board (Version 3.0) is the ultimate pocket-sized powerhouse for makers, students, and professional engineers who want to graduate from standard 8-bit microcontrollers without breaking the bank.

Don’t let its ultra-compact, breadboard-friendly size fool you. Driven by a 32-bit ARM Cortex-M4 core running at 84 MHz, this board delivers crisp, hardware-accelerated performance that leaves classic development boards in the dust. Version 3.0 brings improved power stability, clean routing, and a modern USB-C interface to your workbench.

Why Youll Love It

• The Ultimate Upgrade: Seamlessly transition from basic Arduino boards to the high-performance world of 32-bit ARM architecture.

• Modern USB-C Interface: No more hunting for old cables. Features a robust USB-C connector for power, programming, and native USB OTG functionality.

• Hardware Floating Point Unit (FPU): Perfect for real-time sensor processing, math-heavy algorithms, and smooth motor control.

• Massive Software Support: Code your way. Fully compatible with MicroPython, CircuitPython, Arduino IDE, STM32CubeIDE, and Rust.

• Dual Crystal Oscillators: Equipped with a 25 MHz high-speed crystal for the main clock and a 32.768 kHz low-speed crystal for the internal Real-Time Clock (RTC).

Technical Specifications

What’s V3.0 All About?

The V3.0 layout optimizes power delivery to prevent voltage drops during heavy use with external Wi-Fi, Bluetooth, or display peripherals. It also features crisp, high-contrast pin labeling on both sides of the board, meaning less time squinting at pinout diagrams and more time coding.

Additionally, the USB-C structural pins are reinforced to withstand repetitive plugging and unplugging on your testbench.

What’s Included & Pro Tips

What’s in the Box?

• 1x STM32F401CCU6 V3.0 Development Board

• 2x 40-pin Male Header Strips (Unsoldered for maximum layout flexibility)

• 1x 4-pin Right-Angle Header (For the SWD debugging port)

Pro Tip: How to flash without a debugger

Want to flash your code instantly? Hold down the BOOT0 button, press and release the NRST (Reset) button, and release BOOT0. The board will enter its native USB DFU bootloader mode, allowing you to upload firmware directly over your USB-C cable!
