e.After formatting the TF card, the information shown in the figure below will pop up, click OK.

4)Download the compressed package of the Linux operating system image file you want to burn from the data download page of Orange Pi, and then use the decompression software to decompress it. In the decompressed file, the file ending with ".img" is the image file of the operating system. The size is generally more than 1GB<br>

c) Finally click "Write" to start burning

</p>

c.After the image writing is completed, click the '''"Exit"''' button to exit, and then you can pull out the TF card and insert it into the development board to start

4)After entering the balenaEtcher download page, please select the Linux version of the software through the drop-down box to download<br>

<br>

<br>

5)After downloading, use unzip to decompress. The decompressed balenaEtcher-1.5.109-x64.AppImage is the software needed to burn Linux image

</div>

8)Then double-click balenaEtcher-1.5.109-x64.AppImage on the graphical interface of Ubuntu PC to open balenaEtcher (no installation required), and the interface after balenaEtcher is opened is shown in the following figure<br>

<br>

9)The specific steps to use balenaEtcher to burn a Linux image are as follows

c.Finally, click Flash to start burning the Linux image to the TF card

</div>

<br>

10)The interface displayed in the process of balenaEtcher burning the Linux image is shown in the figure below. In addition, the progress bar shows purple to indicate that the Linux image is being burned to the TF card.

<br>

11)After the Linux image is burned, balenaEtcher will also verify the image burned to the TF card by default to ensure that there is no problem in the burning process. As shown in the figure below, a green progress bar indicates that the image has been burned, and balenaEtcher is verifying the burned image.

<br>

12)After the successful burning, the display interface of balenaEtcher is shown in the figure below. If the green indicator icon is displayed, it means that the image burning is successful. At this time, you can exit balenaEtcher, and then pull out the TF card and insert it into the TF card slot of the development board.

<br>

<br>

=== '''The method of using the 13pin interface of the development board to expand the USB interface''' ===

1)If you have purchased the 13pin expansion board of Orange Pi, insert the expansion board into the 13pin interface of the development board, you can expand 2 USB interfaces<br>

<br>

<br>

2)If there is no 13pin expansion board, you can use a 4pin 2.54mm DuPont to USB2.0 female cable to expand the USB interface. The specific method is as follows:<br>

b.The schematic diagram of 13pin interface is shown below<br>

<br>

<br>

<br>

c.The wiring of USB2 is as follows<br>

<br>

<br>

d.The wiring of USB3 is as follows<br>

<br>

<br>

e.If you need to connect two USB devices on the 13pin interface at the same time, you will find that the 5V and GND pins on the 13pin interface are not enough. At this time, one of the USB devices can use the 5V and GND pins in the 26pin interface. The location is as shown below shown:<br>
