7. Засвар үйлчилгээ
7.1. Ерөнхий тусламж үйлчилгээ
To ensure the longevity and proper functioning of your ESP32 Expansion Board, keep it in a dry, dust-free environment. Avoid exposure to extreme temperatures, high humidity, or corrosive substances. Do not apply excessive force when connecting or disconnecting components, as this may damage the pins or the board itself.
7.2. Цэвэрлэгээ
If cleaning is necessary, gently wipe the board with a soft, dry, lint-free cloth. Do not use liquid cleaners, solvents, or abrasive materials, as these can damage the electronic components or the board's finish.
8. Алдаа засах
8.1. Эрчим хүчний асуудал
- Самбар асаалттай биш байна: Ensure the DC power supply is within the specified 6.5V-30V range and is correctly connected to the DC jack. Verify that the power control switch is in the 'ON' position.
- Unstable power to external sensors: Check the connections to the 3.3V and GND pins. Ensure the total current draw of your external sensors does not exceed the board's capabilities.
8.2. Pin Compatibility
- ESP32 Development Board does not fit: This expansion board is designed specifically for DIYmall ESP32 Development Boards, particularly those with a 36-pin configuration (like the ESP32-WROOM-32). Ensure your ESP32 development board is compatible with this pin layout. Boards with different pin counts (e.g., 30-pin) will not fit correctly.
