3.1 Driver Installation (CH340G)
The AYWHP Nano V3.0 board uses the CH340G chip for USB communication. Before connecting the board to your computer, you may need to install the appropriate drivers. Most modern operating systems (Windows 10/11, recent macOS, Linux distributions) often have these drivers pre-installed or can automatically download them. If the board is not recognized:
- Search online for "CH340G driver" for your specific operating system.
- Download the driver from a reputable source (e.g., manufacturer's website or a well-known Arduino community site).
- Follow the installation instructions provided with the driver package.
- Κάντε επανεκκίνηση του υπολογιστή σας εάν σας ζητηθεί.
3.2 Ρύθμιση Arduino IDE
To program the Nano V3.0 board, you will use the Arduino Integrated Development Environment (IDE).
- Κατεβάστε και εγκαταστήστε την τελευταία έκδοση του Arduino IDE από την επίσημη πλατφόρμα Arduino. webιστοσελίδα (www.arduino.cc/en/software).
- Connect the Nano V3.0 board to your computer using the provided USB Type-C cable.
- Ανοίξτε το Arduino IDE.
- Μεταβείτε στο Εργαλεία > Πίνακας και επιλέξτε "Arduino Nano".
- Μεταβείτε στο Εργαλεία > Επεξεργαστής και επιλέξτε "ATmega328P (Παλιός φορτωτής εκκίνησης)". Some compatible boards may require the old bootloader option for proper communication. If you experience issues, try this setting.
- Μεταβείτε στο Εργαλεία > Θύρα and select the COM port associated with your Nano board. This will typically appear after connecting the board and installing drivers.
3.3 Soldering Pin Headers
The AYWHP Nano V3.0 boards typically come with unsoldered pin headers. These headers need to be soldered onto the board to allow it to be plugged into a breadboard or connected via jumper wires. If you are new to soldering, seek guidance from experienced individuals or online tutorials to ensure proper connections and avoid damage to the board.
4. Οδηγίες λειτουργίας
4.1 Τροφοδοσία της πλακέτας
The Nano V3.0 board can be powered in several ways:
- USB Type-C: Connect the board to your computer or a 5V USB power adapter using the USB-C cable. This is the most common method for programming and basic operation.
- VIN Pin: Provide an unregulated external power supply between 6V and 12V to the VIN pin.
- 5V ακίδα: Provide a regulated 5V external power supply to the 5V pin.
The board automatically detects and switches to the power source with the highest potential, eliminating the need for manual jumper selection.
4.2 Uploading Sketches
Once the Arduino IDE is configured and the board is connected:
- Άνοιξε έναν πρώηνampτο σκίτσο (π.χ., File > Π.χamples > 01.Βασικά > Blink).
- Κάντε κλικ στο "Upload" button (right arrow icon) in the Arduino IDE.
- The IDE will compile the code and upload it to your Nano board. The RX/TX LEDs on the board will blink during the upload process.
4.3 Bootloader Burning
In rare cases, you might need to burn a new bootloader to your Nano V3.0 board, for example, if it becomes corrupted or if you are using a bare ATmega328P chip. This typically requires another Arduino board (e.g., an Uno) acting as an ISP (In-System Programmer).
