The realization of quadrotor UAV from 0 to 1 (16) UAV MCU driver→GPIO

A series of small four-axis drones will be updated this year, from functional design → mind map → schematic design → PCB Layout → welding PCB → programming code → debugging of the whole machine to record their own growth process!
This small four-axis drone was made during the university years, and now I have a deeper understanding of embedded in work and study, so I want to reorganize the small four-axis, and then realize the flight control design of the large four-axis on this basis. , These will all be done after work!
