This project uses the ESP32 module as the main control unit for the electric skateboard. The ESP32 features a 240 MHz dual-core processor with Wi-Fi/Bluetooth communication capabilities. It is paired with the CH340C serial communication chip for USB debugging and downloading. The board also includes a 3.3V voltage regulator, reset and boot buttons, a three-color indicator light, and a battery voltage detection interface, providing a comprehensive control and feedback system.

Through the use of programmable GPIO pins (such as GPIO 25 and GPIO 26), the system can output key control signals for the motor throttle, brakes, and other functions, ensuring reliable support for speed control and energy management on the skateboard.
