Please help me find out what's the problem [Copy link]

The first design schematic diagram requires: core board, buttons (five-axis button*1, ordinary buttons*2, dip switches*2), buzzer, voltage converter (to 5V, 5V to 3V3, servo voltage converter), sensor interface (gyroscope, tof ranging, four-way electromagnetic*1), camera interface, wireless serial port, screen interface, encoder*2, brushed motor drive interface*1, servo interface.

Please guide me, hope to see what the problem is

Battery powered,

VCCBAT is a few V battery

How many V does the VCCSreer below show? Where did it go?

All software and library files of Lichuang are used.

Be careful when using its library files, and pay attention to checking the consistency of the pins with the actual ones when generating PCB

Two resistors are enough for the FB connection, there is no need for three. It is a waste of space, especially adding an adjustable resistor. It is really unnecessary, and adjustable resistors are not cheap.
