Black STM32 F407VE Development Board


The BLACK_F407VE board features an ARM Cortex-M4 based STM32F407xx MCU with a wide range of connectivity support and configurations. There are multiple version of this board like black_f407ve. Here are some highlights of the BLACK_F407VE board:

  • STM32 microcontroller in LQFP100 package

  • Extension header for all LQFP100 I/Os for quick connection to prototyping board and easy probing

  • Flexible board power supply:

    • USB VBUS or external source (3.3V, 5V)

    • Power management access point

  • Three LEDs:

    • 3.3 V power on (LD0)

    • Two user LEDs: green (LD1), green (LD2)

  • Four push-buttons: RESET, K0, K1 and WK_UP

  • Mini-AB connector

Supported Features

The Zephyr black_f407ve board configuration supports the following hardware features:






nested vector interrupt controller



serial port-polling; serial port-interrupt















CAN controller





CAN feature requires CAN transceiver. Zephyr default configuration uses CAN_2 exclusively, as simultaneous use of CAN_1 and CAN_2 is not yet supported.

Other hardware features are not yet supported on Zephyr porting.

The default configuration can be found in the defconfig file:


Pin Mapping

BLACK_F407VE has 5 GPIO controllers. These controllers are responsible for pin muxing, input/output, pull-up, etc.

left pins right pins bottom and top pins

Default Zephyr Peripheral Mapping:

  • UART_1_TX : PB6

  • UART_1_RX : PB7

  • UART_2_TX : PA2

  • UART_2_RX : PA3

  • USER_PB : PA0

  • LD3 : PD13

  • LD4 : PD12

  • LD5 : PD14

  • LD6 : PD15

  • USB DM : PA11

  • USB DP : PA12

  • CAN1_RX : PD0

  • CAN1_TX : PD1

  • CAN2_RX : PB12

  • CAN2_TX : PB13

  • SPI1 MISO : PB4

  • SPI1 MOSI : PB5

  • SPI1 SCK : PB3

  • SPI1 Flash CS : PB0

  • SPI2 MISO : PC2

  • SPI2 MOSI : PC3

  • SPI2 SCK : PB10

System Clock

BLACK_F407VE System Clock could be driven by internal or external oscillator, as well as main PLL clock. By default System clock is driven by PLL clock at 168MHz, driven by 8MHz high speed external clock.

Serial Port

BLACK_F407VE has up to 6 UARTs. The Zephyr console output is assigned to UART2. Default settings are 115200 8N1. Please note that ST-Link Virtual Com Port is not wired to chip serial port. In order to enable console output you should use a serial cable and connect it to UART2 pins (PA2/PA3).

Programming and Debugging

Applications for the black_f407ve board configuration can be built and flashed in the usual way (see Building an Application and Run an Application for more details).


BLACK_F407VE board includes an ST-LINK/V2 embedded debug tool interface. This interface is supported by the openocd version included in Zephyr SDK.

Flashing an application to BLACK_F407VE

Here is an example for the Blinky application.

Run a serial host program to connect with your board:

$ minicom -D /dev/ttyACM0

Build and flash the application:

# From the root of the zephyr repository
west build -b black_f407ve samples/basic/blinky
west flash

You should see user led “LD1” blinking.


You can debug an application in the usual way. Here is an example for the Hello World application.

# From the root of the zephyr repository
west build -b black_f407ve samples/hello_world
west debug
