  • The onboard LED works as LED1 in programs.
  • The onboard KEY on STM32F411CEU6 boards works as USER_BUTTON pin in programs.
  • You can use the USB peripheral in your programs and connect the board to the PC over the onboard USB connector. An example of using the USB peripheral as USBSerial (12 Mbit/s) is available here.
