Power supply
This development board supports USB Type-C 5V power supply and reserved external
power input interface (as shown by reference number 5 in Figure 3). It is recommended
that the input voltage 5V support current is not less than 1A when other expansion boards
are not inserted, and the input voltage 5V support current is not less than 2A when other
expansion boards are inserted (refer to the actual power consumption of the expansion
board for details). Note: When the external power supply is provided through the reserved
power interface, the power supply voltage input range is 5V-9V, and the load current is
recommended to be I> 2A.

Precautions
Please make sure that the FPC cables of the TP and LCM screens have been inserted
into the corresponding FPC sockets before powering on the development board,
otherwise the TP and LCM screens may be damaged.
If the development board is abnormal, please test the voltage of the three TestPad
points (PP5V, PP3V3_1 and PP3V3_2) on the board first. Among them, the output of
PP3V3_1 is used to supply 3.3v power to the board, PP3V3_2 is used to supply 3.3v power
to the external expansion board, and PP5V is the USB input 5V power supply which also
