Meet your hardware

    We’ll refer to this board as “F3” throughout this book.

    What does this board contain?

    • A STM32F303VCT6 microcontroller. This microcontroller has

      • 48 KiB of RAM.

      • many “peripherals”: timers, GPIO, I2C, SPI, USART, etc.

      • lots of “pins” that are exposed in the two lateral “headers”.

    • An and a magnetometer (in a single package).

    • A .

    • A second microcontroller: a STM32F103CBT. This microcontroller is actually part of an on-boardprogrammer and debugger named ST-LINK and is connected to the USB port named “USB ST-LINK”.

    We’ll use this module to exchange data between the microcontroller in the F3 and your laptop. Thismodule will be connected to your laptop using an USB cable. I won’t say more at this point.
