c.The black Dupont wire needs to be plugged into the GND pin of the 26pin or 13pin interface<br>
d.The positions of the 5V pins and GND pins of the 26pin and 13pin interfaces in the development board are shown in the figure below, Remember not to connect the wrong pin<br>

=== '''The method of using the 13pin interface of the development board to expand the USB interface''' ===
<br>
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>
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>
a.First, you need to prepare a 4pin 2.54mm DuPont to USB2.0 female cable (this cable can be bought on Online store, please search and buy by yourself), as shown in the following figure:<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>
