| # Meet your hardware |
| |
| Let's get familiar with the hardware we'll be working with. |
| |
| ## STM32F3DISCOVERY (the "F3") |

| |
| We'll refer to this board as "F3" throughout this book. |
| |
| What does this board contain? |
| |
| - A STM32F303VCT6 microcontroller. This microcontroller has |
| - A single core ARM Cortex-M4F processor with hardware support for single precision floating point |
| operations and a maximum clock frequency of 72 MHz. |
| |
| - 256 KiB of "Flash" memory. (1 KiB = 10**24** bytes) |
| |
| - 48 KiB of RAM. |
| |
| - many "peripherals": timers, GPIO, I2C, SPI, USART, etc. |
| |
| - lots of "pins" that are exposed in the two lateral "headers". |
| |
| - **IMPORTANT** This microcontroller operates at (around) 3.3V. |
| |
| - An [accelerometer] and a [magnetometer][] (in a single package). |

| |
| - A [gyroscope]. |

| |
| - 8 user LEDs arranged in the shape of a compass |
| |
| - A second microcontroller: a STM32F103CBT. This microcontroller is actually part of an on-board |
| programmer and debugger named ST-LINK and is connected to the USB port named "USB ST-LINK". |
| |
| - There's a second USB port, labeled "USB USER" that is connected to the main microcontroller, the |
| STM32F303VCT6, and can be used in applications. |
