STC32G12K128 microcontroller development board (verified successfully)

I. The microcontroller section
uses the STC32G12K128-LQDP chip as the main controller, employing a Type-C interface and a CH340N chip for power supply and program download. Flash storage uses an M24C02 chip, and all pins are brought out via header pins.
II. The power module
uses an RT8289GSP chip to reduce the external power supply voltage to 5V, and then uses an RT9013 chip to further reduce the 5V voltage to 3.3V. The protection circuit consists of a thermistor and a fuse. A jumper cap connected to the voltage synchronization terminal powers the microcontroller (the jumper cap needs to be removed when using USB power).
III. The motor drive section
uses a TB6612FNG chip to drive the DC motor. This requires an external power supply voltage of at least 11.1V (3 seconds). The interface includes two sets of PWM inputs, a motor direction input, and an encoder data interface.
IV. Demonstration section
