* 4. Hardware Part

This project uses an STM32 microcontroller as the core, designed using JLCPCB EDA Professional Edition, and downloaded via the ST-Link interface. It uses a plug-in design for easy portability and assembly, and mainly uses a Bluetooth module, a 2.4G module, a DC-DC step-down module, and a gyroscope module for communication, supplemented by an LCD screen for information display and debugging. The remote control board has six buttons corresponding to forward, backward, left and right, reverse gear, and forward gear, enabling multiple ways to control the small cars.
The following is a partial schematic diagram:
Vehicle Board:
When routing the PCB, pay attention to the distinction between power lines and signal lines, and shield external signals to reduce ripple in the step-down circuit, thus making the 3.3V output more stable.
Remote Control Board:
*5. Software:

This project is mainly developed using Keil5 software in conjunction with the standard library. First, modular programming is performed on each peripheral, and then the logic is written in the main function. The microcontroller HEX file is downloaded via ST-Link.
