Black STM32F407ZGT6

MicroPython board definition files for the black STM32F407ZGT6 dev board.

Brand: ACELEX (unlabeled)

Markings: STM32F4XX STM32_F4VE V3.0 1606

Note: this is a variant of the BLACK STM32F407ZET6 board. This board has a STM32F407ZG MCU instead of a STM32F407ZE and 1024 Kb of flash memory instead of 512 Kb.

You can buy one for around $16 USD (Dec 2017) on AliExpress.

Build and deploy the firmware:

  • Clone the board definitions to your MicroPython ports/stm32/boards folder.
cd micropython/ports/stm32/boards
git clone https://github.com/SpotlightKid/BLACK_F407ZG.git
  • Disconnect the board from USB
  • Set BOOT0 jumper to ON (BT0->3V3)
  • Connect the board via USB

Warning: The location of the BOOT0 pin is different to where it is located on older, similar boards, e.g. the BLACK STM32F407VET6. It is now the second pin from the top on the outer row on the right side of the board when looking from above and with the USB connector at the top.

cd micropython/ports/stm32
make BOARD=BLACK_F407ZG
make BOARD=BLACK_F407ZG deploy
  • Disconnect the board from USB
  • Set BOOT0 jumper to OFF (BT0->GND)
  • Connect the board via USB
