'''Many unstable phenomena during system power-on and startup are basically caused by power supply problems, so a reliable power adapter is very important. If you find that you are constantly restarting during the startup process, please replace the power supply or Type-C data cable and try again.'''
'''Type-C power interface does not support PD negotiation.'''
'''In addition, please do not connect to the USB interface of the computer to power the development board.'''</big>|}</li></ol>
