Download Design Files

The design files are the ExpressPCB PCB layout and schematic files. These are the same files as used on the last production run, v1.1.

Some questions you may be asking:

Why are these files being given away?

I stopped offering these boards many years ago, so I’ve decided to set the design free.

Can I make derivative works from these files?


While I do not require that you share any changes, I would appreciate it if you did. I want to see what derivatives people are making.

Can I resell the boards I make?

Yes, but please make up a different name other than “PIMETA.” I don’t want people to be confused about the source of the boards.

So where are these files?

Right here. (ZIP, 69 KB)

What’s in the ZIP archive?

pimeta-v1.pcb ExpressPCB board layout
  pimeta-v1.sch ExpressPCB schematic

I have no Gerber files. ExpressPCB is proprietary software that only works with the ExpressPCB manufacturing service. If you would rather have your boards made elsewhere, you may be able to find Gerbers others have redrawn, or you may make your own.
