5. Орнотуу жана иштетүү

5.1 Электр менен жабдуунун параметрлери

The board can be powered through three mutually exclusive methods:

1. USB-to-UART Port and/or ESP32-S3 USB Port: Connect either one or both Type-C USB ports to a computer or a 5V USB power adapter. This is the recommended power supply method.
2. 5V and G (GND) Pins: Provide 5V DC power directly to the designated 5V and GND pins on the board.
3. 3V3 and G (GND) Pins: Provide 3.3V DC power directly to the designated 3V3 and GND pins on the board.

5.2 Аппараттык туташуу

To begin development, connect the board to your computer:

• Use a USB Type-A to Type-C cable or a Type-C to Type-C (CC) cable. Ensure the cable supports data communication, not just charging.
• Connect the cable to either the USB-to-UART Port or the ESP32-S3 USB Port on the development board. The USB-to-UART Port is typically used for initial setup and flashing.

5.3 Software Setup and Flashing

To set up the development environment and flash an application onto your board, follow these general steps:

1. Драйверлерди орнотуу: Ensure your operating system recognizes the USB-to-UART bridge chip (e.g., CH343P). Drivers may be automatically installed or require manual installation.
2. Орнотуу иштеп чыгуу чөйрөсү: Download and install the Espressif IoT Development Framework (ESP-IDF) or a compatible IDE such as Arduino IDE with ESP32 board support, or PlatformIO.
3. Configure IDE/SDK: Select the correct board model (e.g., "ESP32S3 Dev Module") and configure flash size (e.g., 16MB) and PSRAM settings as needed for your project.
4. Кодду жазуу/жүктөө: Develop your application code or load an example долбоору.
5. Flash Firmware: Connect the board via the USB-to-UART port. Put the board into download mode by holding down the Жүктөө button, then pressing and releasing the RST button, and finally releasing the Жүктөө button. Use the IDE or esptool.py to flash your compiled firmware onto the board.
6. Колдонмону иштетүү: After successful flashing, press the RST button to restart the board and run your new application.
