Description

Black Pill STM32 Arm Controller Module with USB-C socket

⚠️ It’s not physically compatible with the Pro Micro. The PCB needs to be specifically designed for it.

Specs:

  • Powerful Arm Cortex M4 core with high clock speed
  • A lot more memory, flash and I/O pins than the Pro Micro
  • USB-C socket
  • DFU bootloader, can be programmed easily using dfu-util
  • Runs on 3.3 V, but many pins are 5 V-tolerant
  • On-board reset and boot buttons
  • Comes with 2 20-pin headers and 1 4-pin programming header (not required thanks to the USB bootloader)

F401

  • STM32F401CCU6 MCU
  • 84 MHz clock speed
  • 64 kB SRAM
  • 256 kB flash
  • 35 I/O pins

F411

  • STM32F411CEU6 MCU
  • 100 MHz clock speed
  • 128 kB SRAM
  • 512 kB flash
  • 35 I/O pins

Both versions are pin-compatible. (For comparison: the ATmega32u4 on the Pro Micro has 16 MHz clock, 2.5 kB SRAM, 32 KB flash and only 18 I/O pins.)

To flash the QMK firmware to the Black Pill connect it to your computer and set it to bootloader mode:

  • Press and hold the BOOT0 button.
  • Press and release the NRST button.
  • Release the BOOT0 button.

The timing of press and release is crucial so you’ll probably will have to try a few times until you’ll get the hand of it.
