Quadcopter control system based on STM32 microcontroller (schematic PCB, program source code)

Overview

This work is designed for a small quadcopter. It adopts an integrated design idea, that is, the fuselage and processor board are used as a whole. The processor of the small quadcopter uses the STM32F103 chip, the sensor uses the MPU6050, and the receiving board uses the STM32F4 Discovery development board. , connected to the processor using the IIC bus; the NRF24L01 wireless chip is used on the remote control board, and the attitude display and control of the small quadcopter is completed through the host computer using a self-defined protocol; a coreless cup motor and two pairs of forward and reverse propellers are used. The battery uses a 4.1V lithium battery; the power control part of the entire system uses a 662K voltage regulator chip, which can ensure the stability of the power supply and ensure the stable and reliable operation of the system.
