Is there any interest in another CMoy PCB? Because if theres enough i will let a professionell company produce some.

Length: 1.34inch (3,40cm)
Width: 1.68inch (4,6cm)
FR-4 Fiberglass with 35um Copper

BOM:
1x Alps RK097 Potentiometer with integrated switch
1x BurrBrown OPA 2134
1x TLE2426 TO226
1x 220uF electrolytic capacitor
1x LED 3mm
2x Stereo Earphone Jack 3,5mm (See Here!!!)
2x 0,1uF Film Capacitor
2x 100k Resistor
2x 10k Resistor
2x 1k Resistor
2x 47 or Jumper
also u need a resistor for the LED, Cable, a Battery, Standart Solder Tools, a case and the PCB of course.

The Schematic:


The PCB:


Finally:


The price will result in the Interest. Also a white item print is possible.

If you are Interested, have questions or have ideas to improve something please do not hesitate to post. Also you can post comments or critics.

I hope for your Interest

Some layout comments:
  1. TLE and PSU caps: I personally would use a pair of caps on the output of the TLE rather than one on the input. 470u. 25V. Pana FMs
  2. Your input caps seem rather small. It would make it difficult to find a 0.47uf (or even 1uf) cap which would fit.
  3. I assume this is using a ground plane for the top layer? If not, why not?
  4. I would check the pot and jack spacing to the board edge to ensure they are flush (seems a bit far away, but I could be wrong).
Otherwise, looks nice.

My Standart 0.047 Caps are that size, 5mm lead spacing
I will edit the PSU and make the board smaller

Thanks for commenting
