{| class="wikitable" style="background-color:#ffffdc;width:800px;" |-| <big>'''The power supply method we recommend for the development board is to use the 5V/2A or 5V/3A Type C interface power cord to plug into the Type C power interface of the development board for power supply. If you need to use the 5V pin in the 26pin or 13pin interface to power the development board, please make sure that the power cable used can meet the power supply requirements of the development board. If the use is unstable, please switch back to the Type C power supply.'''</big>|}
# First, you need to prepare a power cord as shown in the figure below
