I'm going to explain how this player is build on the example of ergotech u22, which is a S1mp3 player. The player consists of two circuit boards.

  1. LCD screen, with connector (fragile!)
  2. Volume Up button
  3. Play/Pause and On/Off button
  4. Volume Down button
  5. Red backlight component wire
  6. Green backlight component wire
  7. Blue backlight component wire
  8. Backlight ground wire - you can dim backlight by soldering the resistor in the middle of this wire

On the backside there is nothing interesting, just circuits and one screw
