12864 display connection 32 minimum version set of serial display circuit board

Overview

After testing, the serial port can be successfully connected to display the content.
This side is connected to the 12864 display,

and this side is connected to the smallest version of the STM

PCB. Remember to open the layer to see it. I don’t know why it’s stuck.
