Hardware System of Small Four-rotor Aircraft Based on STM32
In order to realize the controllable and stable flight of the four-rotor aircraft,a hardware system design scheme based on STM32F411 controller combined with low-power motor is proposed in this paper.Inertial measurement module MPU9250 and pressure sensor FBM320 are used to measure the attitude altitude of the flight control system.ESP8266 wireless transparent transmission and NRF24L01 transceiver module are used for information exchange with the command and control system.For external power 903052 lithium battery,the modular circuit design.The mathematical mod-el based on dynamic components can predict flight duration and so on.
