| What does this board contain? |
| |
| - A [STM32F303VCT6](https://www.st.com/en/microcontrollers/stm32f303vc.html) 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. |
| |
| - A variety of integrated peripherals such as timers, I2C, SPI and USART. |
| |
| - General purpose Input Output (GPIO) and other types of pins accessible through the two rows of headers along side the board. |
| |
| - A USB interface accessible through the USB port labeled "USB USER". |
| |
| - An [accelerometer](https://en.wikipedia.org/wiki/Accelerometer) as part of the [LSM303DLHC](https://www.st.com/en/mems-and-sensors/lsm303dlhc.html) chip. |
| |
| - A [magnetometer](https://en.wikipedia.org/wiki/Magnetometer) as part of the [LSM303DLHC](https://www.st.com/en/mems-and-sensors/lsm303dlhc.html) chip. |
| |
| - A [gyroscope](https://en.wikipedia.org/wiki/Gyroscope) as part of the [L3GD20](https://www.pololu.com/file/0J563/L3GD20.pdf) chip. |
| |
| - 8 user LEDs arranged in the shape of a compass. |
| |
| - A second microcontroller: a [STM32F103](https://www.st.com/en/microcontrollers/stm32f103cb.html). This microcontroller is actually part of an on-board programmer / debugger and is connected to the USB port named "USB ST-LINK". |
| |
| For a more detailed list of features and further specifications of the board take a look at the [STMicroelectronics](https://www.st.com/en/evaluation-tools/stm32f3discovery.html) website. |
| |
| A word of caution: be careful if you want to apply external signals to the board. The microcontroller STM32F303VCT6 pins take a nominal voltage of 3.3 volts. For further information consult the [6.2 Absolute maximum ratings section in the manual](https://www.st.com/resource/en/datasheet/stm32f303vc.pdf) |
