Fastbit Embedded STM32F303CCT6 Nano Board User Manual
Introduction
The Nano board allows users to easily develop applications with the STM32F303CCT6 micro controller with the Arm Cortex-M4 32-bit core.
Based on STM32F303CCT6, it includes one MPU6050 (is a 3-axis gyroscope and a 3- axis accelerator sensor), LEDs, push-buttons and a mini USB port.

Power supply and power selection
- The power supply is provided either by the host PC through the USB cable or via the SWD port using an ST-Link connection.
- U2 regulates the 5V input from USB to provide a steady 3.3V output.
Note: Don’t connect external power supply to header sockets.
LEDs
- D1 PWR: red LED indicates that the board is powered.
- User D2: blue LED is a user LED connected to the I/O PA1 of the STM32F303CCT6.
- User D3: green LED is a user LED connected to the I/O PA2 of the STM32F303CCT6.
- User D4: red LED is a user LED connected to the I/O PA3 of the STM32F303CCT6.
- SW1 RESET: Push button connected to NRST is used to RESET the STM32F303CCT6.
- SW2 USER: User button is connected to the I/O PA0 of the STM32F303CCT6.
- SW3 BOOT0: Push button connected to BOOT0 is used to toggle the boot mode of the STM32F303CCT6.
BOOT0 Boot Mode 0 Main flash memory 1 System memory Table 1: Boot modes
Note: By default, the micro controller runs the application code from the main flash memory. To change this behaviour, use the BOOT0 button.
- Press the BOOT0 button and then press the reset button.
- This action makes the micro controller to run the built-in boot loader from the system memory (i.e., micro controller enters the boot loader mode).
Axis (Gyro + Accelerator) MEMS Motion Tracking
- MPU6050 sensor is a low power, low cost, and high-performance 6-axis (Gyro + Accelerator).
- The MPU6050 devices combine a 3-axis gyroscope and a 3-axis accelerometer on the same silicon die, together with an onboard Digital Motion Processor (DMP), which processes complex 6-axis Motion Fusion algorithms.
- The STM32F303CCT6 micro controller controls this sensor through the I2C interface.
OSC Clock
- LSE: OSC 32.768 kHz clock supply
Refers to an external oscillator running at 32.768 kHz. It typically provides a low frequency clock source for real-time clocks (RTC) or other timing-sensitive functions.Pin Name Pin Function PC14 OSC32_IN PC15 OSC32_OUT - HSE: OSC 8 MHz clock supply
Refers to an external oscillator running at 8MHz. It provides a higher-frequency clock source suitable for driving the core processing unit or other high-speed peripherals.Pin Name Pin Function PF0 OSC_IN PF1 OSC_OUT
USB to UART bridge
- The USB to UART bridge facilitates communication between a computer and a STM32F303CCT6, with Stuart and UART1Rx serving as the transmit and receive pins, respectively, connected to pins PA9 and PA10 on the micro controller.
Pin Name Pin Function PA9 UART1_Tx PA10 UART1_Rx
