4. Kurulum Kılavuzu
Before using your Aokin ESP32 development board, follow these steps to ensure proper setup:
4.1 Sürücü Kurulumu
The board uses a CP2102 USB to UART bridge. You may need to install the appropriate drivers for your operating system. Drivers can typically be found on the Silicon Labs webalan:
4.2 Kartın Bağlanması
Connect the ESP32 board to your computer using a micro-USB cable. The board is designed to fit on a standard solderless breadboard, making prototyping convenient.

4.3 Initial Program Download (Important Tip)
When downloading a program to the development board, it is often necessary to manually put the board into programming mode. This typically involves pressing and holding the IO0 button for 1-2 seconds during the upload process, especially when the Arduino IDE or similar tools indicate the start of the upload sequence.
5. Kullanım Talimatları
The Aokin ESP32 board offers flexible operating capabilities for various embedded projects.
5.1 Programlama Ortamları
The board is compatible with popular development environments:
- Arduino IDE'si: Widely used for its simplicity and extensive library support.
- NodeMCU (Lua): For Lua-based scripting and rapid prototyping.
- MikroPython: For Python-based programming on microcontrollers.
5.2 Wi-Fi and Bluetooth Modes
The ESP32 supports three primary Wi-Fi operating modes:
- İstasyon (STA) Modu: The ESP32 connects to an existing Wi-Fi network (e.g., your home router).
- Erişim Noktası (AP) Modu: The ESP32 creates its own Wi-Fi network, allowing other devices to connect to it.
- AP+STA Coexistence Mode: The ESP32 operates as both an Access Point and a Station simultaneously.
5.3 Pin Bağlantı Şeması
Understanding the pinout is crucial for connecting external components and sensors. Refer to the diagram below for the pin assignments.

6. Bakım
The Aokin ESP32 development board is designed for durability and requires minimal maintenance. Keep the board clean and free from dust and moisture. Avoid exposing it to extreme temperatures or static electricity. No user-serviceable parts are inside the module itself.
7. Sorun Giderme
If you encounter issues with your ESP32 development board, consider the following common troubleshooting steps:
7.1 Program Upload Issues
- IO0 Düğmesi: If your program fails to upload, ensure you are pressing and holding the IO0 button (sometimes labeled "BOOT" or "FLASH") during the upload process, especially when the IDE indicates it's attempting to connect or upload. Release the button once the upload begins.
- USB Cable/Port: Try a different USB cable or a different USB port on your computer. Faulty cables or insufficient power from a USB port can cause upload failures.
- Sürücü Sorunları: Verify that the CP2102 drivers are correctly installed and recognized by your operating system.
- Board Selection: In your IDE (e.g., Arduino IDE), ensure you have selected the correct board model (e.g., "ESP32 Dev Module" or similar) and COM port.
7.2 Physical Defects
- Bükülmüş Pimler: Carefully inspect the pins on the board. If any are bent, gently straighten them.
- Solder Bridges: In rare cases, small solder bridges between pins can occur during manufacturing. Visually inspect the pins for any unintended connections and carefully remove them if found (e.g., with a fine soldering iron tip).
