Four-axis aerial photography aircraft circuit scheme is free and open source

Four-axis drone based on STM32. With STM32 as the control core, four-axis aircraft as the carrier, and gimbal as the aerial photography system. The hardware consists of flight control circuit, power management, communication module, power system, frame, and gimbal servo system. The algorithm uses simple and stable quaternion plus complementary filtering as the attitude solution algorithm, and PID as the controller to realize flight, gimbal stabilization and other functions. It has the characteristics of flexibility, lightness, ductility, and good adaptability.
