5. Иштөө нускамалары

5.1. Pinout диаграммасы

Understanding the pinout is crucial for connecting peripherals and programming your board. Refer to the detailed pinout diagram below:

5.2. Basic Programming

Once your development environment is set up and the board is selected:

1. Кодду жазыңыз: Develop your application code (sketch) in C/C++ or MicroPython.
2. Компиляция: Compile your code within the IDE to check for errors.
3. Жүктөө: Click the 'Upload' button in your IDE. The IDE will compile and then upload the firmware to the T7 S3 board via the USB-C connection.
4. Монитордун сериялык чыгышы: Use the Serial Monitor in your IDE to view debug messages or data from your board.

5.3. Башкармалыкты башкаруу

• USB Type-C: The primary power source is the USB Type-C port, which also handles data communication.
• Battery (JST Connector): The 1.25mm JST 2P connector allows you to connect a compatible LiPo battery for portable applications. The board includes a blue charging indicator LED.

5.4. Баскычтар

• Калыбына келтирүү баскычы: Press this button to restart the ESP32-S3 module.
• Boot Button: This button is typically used to put the ESP32-S3 into bootloader mode for flashing new firmware. Hold down the Boot button, press and release the Reset button, then release the Boot button.
• Power (PWR) Switch: Controls the main power supply to the board.
