UAV code and documentation based on STM32

The structural characteristic of a quadcopter is that it is equipped with a rotor on each of its four corners, which are driven by motors. The blades can rotate forward or reverse. In order to maintain the stable flight of the aircraft, the quadcopter is equipped with 3-directional gyroscopes and 3-axis acceleration sensors to form an inertial navigation module. It also uses an electronic controller to ensure its fast flight.

42 W high power factor constant voltage output flyback converter based on ICL8810

REF_ICL8810_LED_42W_PSR This 42 W reference design uses Infineon's high power factor flyback controller ICL8810. The evaluation board is a constant voltage (CV) secondary side regulation (SSR) system designed for use with a constant current (CC) converter for LED lighting applications.

USB-C "switch", hardware open source, firmware provided

The basic functions of USB-C are supported, such as high-speed communication and charging functions. Then this design solves the problem of painless switching between one host and multiple devices, or one device and multiple hosts.
