Precautions for assembly and use
During assembly and use，Please pay attention to the following issues
one，Short circuit problem between bare board and peripheral devices
two，During the installation and fixation process，Avoid deformation of bare boards due to fixation reasons
three，installTCP When touching the screen，Pay attention to the direction of the adapter board
four，During peripheral installation，Pay attention to peripheralsIO Level and current output issues
five，When connecting via serial port，Pay attention to whether it is connected 232 or 485 equipment，as well as TX and RXIs the connection correct。
six，Pay attention to whether the input voltage and current are correct
