2. Drugi konec kabla USB-C priključite na prosta vrata USB na računalniku.
3. The power LED on the board should illuminate, indicating it is receiving power.

3.3 Nastavitev razvojnega okolja

To program the ESP32 board, you will need a suitable Integrated Development Environment (IDE). Popular choices include:

• Arduino IDE: Install the ESP32 board package through the Boards Manager.
• PlatformaIO: A powerful ecosystem for IoT development, compatible with various IDEs like VS Code.
• ESP-IDF: Espressif's official IoT Development Framework for more advanced applications.

Refer to the documentation for your chosen IDE for detailed installation and configuration instructions for ESP32 boards.

4. Navodila za uporabo

4.1 Uploading Code

1. Open your chosen IDE (e.g., Arduino IDE).
2. Select the correct board model (e.g., "ESP32 Dev Module" or similar) and the COM port assigned to your ESP32 board.
3. Write or load your program (sketch).
4. Click the "Upload" button. The IDE will compile the code and attempt to upload it to the board.
5. During upload, you may need to press and hold the BOOT button on the ESP32 board, then press the EN (reset) button, and release EN, nato spustite BOOT once the upload process begins. Some boards may enter programming mode automatically.

5. Vzdrževanje

To ensure the longevity and proper functioning of your ESP32 development board, follow these maintenance guidelines:

• Ravnajte previdno: Izogibajte se padcem plošče ali njeni izpostavljenosti fizičnim udarcem.
• Statična razelektritev: Always handle the board in a static-safe environment to prevent damage from electrostatic discharge (ESD).
• Ohranjajte na suhem: Protect the board from moisture and liquids.
• Čistoča: Keep the board free from dust and debris. Use a soft, dry brush or compressed air for cleaning.
• Napajanje: Use a stable 5V DC power supply via the USB-C port. Avoid over-voltage or reverse polarity.
• Shranjevanje: Store the board in an anti-static bag when not in use.

6. Odpravljanje težav

6.1 Board Not Detected by Computer

• Preverite kabel USB: Ensure the USB-C cable is functional and properly connected. Try a different cable.
• Install CH340 Driver: Verify that the CH340 USB-to-serial driver is correctly installed on your operating system.
• Poskusite z različnimi vrati USB: Connect the board to another USB port on your computer.

6.2 Code Upload Fails

• Correct Board and Port: Ensure the correct ESP32 board type and COM port are selected in your IDE.
• Način zagona: Manually put the board into bootloader mode by holding the BOOT button, pressing and releasing EN, then releasing BOOT when the upload starts.
• Napajanje: Ensure the board is receiving sufficient power. Some complex sketches might require more power than a standard USB port can provide.
• Serial Monitor: Close any open serial monitors in your IDE before attempting to upload code.
