Peripherals
Display screen
If you don’t have an idle screen, just spend over 200 to buy a 7-inch one. It is best to plug in the power supply by yourself and not use the motherboard to supply power.
sd card
It is recommended to get a 128G of u3. Use Samsung's.
Wireless wifi
edmax or something, the official recommendation. More than 70.
shell
Plastic ones will do.
other
Keyboard, mouse, usb extender, camera, oled display, etc. can not be obtained according to demand.
Burning system
The only thing to pay attention to, don't plug in the usb2.0 interface, plug in the interface above 3.0, or the system will report an error if it is burned.
