Gerbers

This is a 2-layer PCB which can be fabricated from the files in the gerbers directory. It is a simple design which can be made on a mill with no soldermask as long as it has plated-through holes. The most important files are:

  • copper_top.gbr: top copper
  • copper_bottom.gbr: bottom copper
  • profile.gbr: board outline
