PCBs!!!

A project log for China cheap MP3 player hack

I want to hack cheap china 2 dollar MP3 player. Next step is design my own small dev board with STM32 and put it into original package.

Today I receive my package:

Some errors ( :( )

- wrong position of LCD pads - should be more in right and down position

- soldermask on "buttons" - but I can easy fix this

- a little different pinout to jack plug, but it is still ok to solder

Quality of PCB - GREAT! :)
