Adding a custom USB socket to the STM32 NUCLEO-F746

I’m currently building a design on the STM32F7 which I want to later port to a F4-NUCLEO board and eventually my own design so I want to test the USB host without the supplied electronics.

In order to do this I built a small USB breakout adapter and tried directly connecting this to 5V (for power) and PA11/PA12 (for USB).  The breakout was made by simply soldering some header pins to a USB socket.

I then attached the USB socket to CN12 as shown below.

The complete pinout for CN12 can be found here

You will need to connect the pins on the usb connector as shown below:

  1. VBUS (+5v)
  2. PA11
  3. PA12
  4. GND
