Oshpark Gerber Cam Job (Eagle)


I was a loyal user of BatchPCB a side project of SparkFun. Recently, their service was moved to OSH Park which supports Eagles 6.4 or higher board files natively. However I always liked the fact that SparkFun provided with their own cam job that works just perfect. And since these gerber files are the actual standard in the industry (i think…) well i made my own for OSH Park.

Remember, don’t leave any layer empty (that goes for Top and Bottom Silk Layers)

The layout is like this:

  • boardname.GTL Top Layer (top, pads, vias)
  • boardname.GBL Bottom Layer (bottom, pads, vias)
  • boardname.GTS Top Soldermask (tStop)
  • boardname.GBS Bottom Soldermask (bStop)
  • boardname.GTO Top Silkscreen (tPlace)
  • boardname.GBO Bottom Silkscreen (bPlace)
  • boardname.GKO Board Outline (Dimension)
  • boardname.XLN Drills (Holes, Drills)

I hope it’s good and that it works for you!

So, here is my latest design, basically it’s a USB stick that you plug into your computer and automatically starts broadcasting your music throughout the FM radio. In other words: Plug and play.

It features Play, Pause, Stop, Next, Previous, Volumen + and Volumen – controls. And it works in any OS. No drivers required.

The carrier frequency can be adjusted using a variable coil. It can transmit between 88MHz and 108MHz. It drains its power from the USB but an additional amp can be plugged into the antenna output to increase the transmitter power and therefore obtain a greater range.
