This is two-sided PCB for YAMPP-3/USB and 3,5'' HDD, designed in Sprint Layout ver. 4.0
Top side I make with laser printer technology.
Bottom side I make manually (with special marker for PCB).
On this board LP2980-3.0 replaced by LM317LMX (SO-08 package, 100mA).
5v switching power supply was removed.

Player works fine!

I try FAT32 and YADL versions, displays SunLike SC2004C or Nokia 3310 LCD.
And I use 30MHZ crystal on VS1001K for normal playing 320kbps or VBR MP3's.
