Some of the more expensive 0603 packaged chip capacitors in the original version were replaced with relatively cheap electrolytic capacitors.
OLED screens require you to solder capacitors yourself. Of course, you can also just buy a finished OLED screen and fly the wires.
I designed this board for my own use, and there is a CAD file of the panel below.
Then, because I just drew it casually, wiring and so on, I just let it go emmmm, after all, I am not good at it, so any advice is welcome.
Secondly, there may be some problems with the board? Welcome to point out,
This board has not been verified. I will make a board later and solder it myself to see.
