I am learning to design the sch files.
But really a new bie, hope experienced guys can help to guide how to finish it.
Basically this a IR receive board : receive the IR code and decode it and transfer to master MCU.
I divide it into 2 parts: the hard PCB and soft FPC, compose them with free : 1 PCB + N FPCs.
I can manage simple digital parts, but for analog one, I think they are too miraculous to understand.
