# Connect a high-quality power adapter with a 5V/2A (5V/3A is also available) USB Type C interface
{| class="wikitable" style="background-color:#ffffdc;width:800px;" |-| <big>'''<span style="color:#FF0000">Remember not to plug in a power adapter with a voltage output greater than 5V, as this will burn out the development board.</span>'''
'''<span style="color:#FF0000">Many unstable phenomena during the power-on and start-up process of the system are basically caused by power supply problems, so a reliable power adapter is very important. If you find that there is a phenomenon of continuous restart during the startup process, please replace the power supply or Type C data cable and try again.</span>'''</big>|}

<li><p>Then turn on the switch of the power adapter, if everything is normal, the HDMI monitor can see the system startup screen at this time</p></li>
<li><p>If you want to view the output information of the system through the debugging serial port, please use the serial cable to connect the development board to the computer. For the connection method of the serial port, please refer to [[Orange Pi Zero 3#the section on how to use the debugging serial port|'''the section on how to use the debugging serial port''']]</p></li></ol>
