== Info ==
== Overview ==
=== Leds ===
The STM32 F4VE is a small development board based on the STM32F407VET6 microcontroller.
* '''D0''' (Power LED) — +3.3V rail
It breaks out all CPU pins via two 2×24 pin headers and supports expansion through
* '''D1''' (User LED 1) — PA6 (sink)
multiple peripheral connectors.
* '''D3''' (User LED 2) — PA7 (sink)

=== Makefile ===
No STM32CubeMX gerar o projecto no formato '''Makefile'''.
 
=== Compilar ===
Usar o [https://developer.arm.com/open-source/gnu-toolchain/gnu-rm GNU ARM Embedded Toolchain].
 
=== Flash ===
É preciso usar um programador '''ST-Link V2''' e o software [https://github.com/texane/stlink stlink].
<syntaxhighlight lang="shell">
st-flash write build/blinky.bin 0x8000000
</syntaxhighlight>
 
=== Debug ===
Correr o '''st-util''' num terminal separado. E depois corre-se o gdb com:
<syntaxhighlight lang="shell">
arm-none-eabi-gdb --eval-command="tar extended-remote :4242" build/blinky.elf
</syntaxhighlight>
 
== Description ==
Core407V is a small STM32 development board that features an STM32F407VET6 device as the microcontroller, supports further expansion. It is ideal for starting application development with STM32F family.


Board marked "STM32F4XX STM32_F4VE V2.0  1509" on the back.

== Board Features ==
=== Warnings ===
* Onboard microSD card slot
* '''Warning:''' The +5V pins are directly connected to the USB +5V pin with no protection. Do not power the board through USB and an external power supply at the same time.
* RTC backup battery: CR1220
* '''Warning:''' The board has an extra pull-up resistor on D+ (R21, 1.5kΩ) that violates the USB specification when the MCU's internal pull-ups are also active. This may cause USB errors. USB data lines also have 22Ω series resistors (R18, R19) for protection.
* Wireless: nRF24L01 interface header
* SPI Flash: W25Q16JV (2MiB, on SPI1)
* FSMC LCD TFT interface (16×2 header)
* JTAG/SWD header (2×10)
* Mini USB (VCP via ST VCP driver)
* Serial header (USART1: PA9/PA10)
* 4 buttons: RST, WK_UP, K0, K1
* 2 user LEDs + 1 power LED
* BOOT0 and BOOT1 jumpers
* RTC crystal (32.768kHz) + 8MHz HSE crystal
* All CPU pins broken out (2×24 headers)


=== Avisos ===
== Microcontroller ==
* '''Atenção:''' Os pinos +5V estão directamente ligados ao USB. Não alimentar pelo USB e por fonte externa simultaneamente.
* '''Atenção:''' A placa tem um resistor pull-up extra em D+ (R21) que viola a especificação USB quando os pull-ups internos do MCU também estão activos. Pode causar erros de USB.

Overview

The STM32 F4VE is a small development board based on the STM32F407VET6 microcontroller. It breaks out all CPU pins via two 2×24 pin headers and supports expansion through multiple peripheral connectors.

Board marked "STM32F4XX STM32_F4VE V2.0 1509" on the back.

Name STM32 F4VE
Part STM32_F4VE
Origin China
PCB Color Black
PCB Size 62mm × 85mm
Mounting 4× M3 holes

Warnings

  • Warning: The +5V pins are directly connected to the USB +5V pin with no protection. Do not power the board through USB and an external power supply at the same time.
  • Warning: The board has an extra pull-up resistor on D+ (R21, 1.5kΩ) that violates the USB specification when the MCU's internal pull-ups are also active. This may cause USB errors. USB data lines also have 22Ω series resistors (R18, R19) for protection.

Connectors & Pinouts

GPIO Headers

Two 2×24 pin headers (2.54mm, male) break out all GPIO.

Note: PB3, PB5, PB6, PB7 are shared with the nRF24L01 header (SPI1). PB3/PB4 are also used for JTAG (TDO/TRST). PA13/PA14 are JTAG only and do not appear on the GPIO headers.
