4. خطوات التشغيل

4.1 Pre-Power-On Preparation

1. Check the board appearance: Ensure there are no damaged components, loose solder joints, or foreign objects (such as solder slag) on the board. Focus on checking the power interface and core chip pins for short circuits or misalignment.
2. Prepare tools and documents: Prepare a computer (with corresponding development software installed), anti-static wristband, digital multimeter (for optional short-circuit detection), and print the board’s schematic and BOM list if necessary.
3. Connect peripherals (if needed): Use jumper wires to connect external sensors, displays, or other modules to the board’s expansion interface. Ensure the connection direction is correct (matching pin definitions) to avoid reverse connection damage.
4. التحقق من مصدر الطاقة: Confirm the power adapter’s output voltage and current match the board’s requirements. For USB-powered boards, ensure the USB port can provide sufficient current (avoid using low-power USB hubs).

4.2 Power-On Operation

1. قم بتوصيل مصدر الطاقة: Insert the power adapter into the board’s power interface, or connect the USB cable to the board’s USB port and the computer’s USB port.
2. Power on the board: Turn on the board’s power switch (if equipped). Observe the indicator lights on the board–usually, a power indicator (red) will light up, indicating the board is powered on normally.
3. Verify power status: Use a multimeter to measure the key voltage rails (such as 3.3V and 5V) on the board to confirm they are within the normal range. If the voltage is abnormal, power off immediately and check for short circuits or power supply issues.

4.3 Programming & Debugging

1. Install development software: Install the corresponding programming software (e.g., Arduino IDE, Keil MDK, VS Code) on the computer, and install the necessary drivers for the board’s programming interface (e.g., USB-to-UART driver).
2. Connect the programming interface: Ensure the board is connected to the computer via the USB cable (or dedicated programming cable). The computer should recognize the board’s COM port (check in Device Manager).
3. Load and compile code: Open the development software, create a new project or load an existing program, compile the code to check for errors. If there are compilation errors, modify the code and recompile.
4. Upload code to the board: Select the correct board model and COM port in the software, then click the ‘Upload’ button to send the compiled code to the development board.
5. Debug and test: After the code is uploaded successfully, observe the board’s operation (e.g., indicator lights, peripheral responses). Use the software’s debugging function to troubleshoot if the program does not run as expected.

5. قيود الاستخدام
The development board is designed for development and prototyping purposes, and its use is subject to the following limitations. Exceeding these limitations may cause equipment damage or aect performance:
· المجلدtage limitation: The input voltage must be within the range specified on the board
(typically 5V ± 0.5V or 3.3V ± 0.3V). Overvoltagالبريد أو undervoltage will damage the board’s components and invalidate the warranty.

· Current limitation: The total current drawn by the board and connected peripherals must
not exceed the maximum current capacity of the power supply and board’s voltage regulators. The board’s 3.3V interface is designed for low-current logic devices (e.g., sensors) and cannot power high-current devices such as motors or servos, which will cause voltage collapse and system failure.
· Temperature limitation: The operating temperature range of the board is -10 ° C to 60 ° C.
Using the board outside this range will reduce component lifespan and may cause unstable operation. Avoid direct sunlight or high-temperature environments.
· Peripheral compatibility: The board’s expansion interface supports standard peripherals,
but some non-standard modules may require additional drivers or modifications. Using incompatible peripherals may cause short circuits or damage to the board.
· Storage limitation: Do not store the board in humid, high-temperature, or corrosive
environments. Store it in an anti-static bag or box to prevent component damage from dust, moisture, or electrostatic discharge.
· Usage scope: This board is for non-commercial, development, and learning purposes only.
It is not suitable for industrial control, medical equipment, or other high-reliability application scenarios without additional protection measures.
6. استكشاف الأخطاء وإصلاحها
If the board fails to work normally, please refer to the following troubleshooting steps before contacting technical support:
· No power indicator: Check if the power supply is connected correctly, the power switch is
turned on, and the power adapter/USB cable is intact. Use a multimeter to check if the power interface has normal voltage.
· Computer cannot recognize the board: Reinstall the USB driver, replace the USB cable or
USB port, and check if the board’s programming interface is damaged.
· Code cannot be uploaded: Confi rm the correct board model and COM port are selected in
the development software, check the programming cable connection, and ensure the board is powered on normally.
· Program runs abnormally: Check the code for errors, verify the peripheral connections (e.g.,
pin defi nitions), and ensure the power supply provides sufficient current (especially when using multiple peripherals).
· Board overheats or emits abnormal odors: Immediately power o the board, check for
short circuits between power and ground, and ensure no high-current devices are connected to the board’s low-current interfaces.
