  • Just a note - this is a great tutorial! EAGLE has changed a bunch over the last 7+ years, so some things either look different, or work differently than spec'ed here. For instance, the CAM file linked to in the article doesn't work with EAGLE 9.6.1 - no output files are generated. Using the 2-layer Default template yields results - but all the files are .GBR extension (with a couple TXT files, too).

    If y'all have some time to update this (and the Schematic tutorial), it might help other folks get started with the newer versions of EAGLE? Otherwise, I was mostly able to figure things out - just took some digging in a couple cases! Thanks!

  • The silk screen labeling in the reference design has a mistake: The order of CTS, VCC, RX, and TX are mixed up.

    Also, CTS is not connected to anything. I'm not sure if that's a mistake or on purpose.

  • my drill files are not matching with the gerber file i generated...what shuld i do...

  • Product engineering covers a whole spectrum of skills that are required in order to create useful and functional devices and machines. Integrated systems are part of product engineering and their main purpose is to be able to combine multiple systems to deliver overarching functionality by working as a complete and whole entity.

  • Where do these Gerber files go? I opened the CAM processor, opened job gerb274x.cam, loaded my .brd file, it showed the path to my board at the bottom of the box, I hit "process job" and something happened with no apparent error messages. But I don't have files with extensions like .GBL or.GTL anywhere on my hard disk.

    I have Eagle 7.3.0 Standard, Win 7

    • It seems Eagle has changed the file extensions. Component side = .cmp Solder side = .sol Top silk = .plc Top mask = .stc Bottom mask = .sts There are also .gpi which looks like a photoplotter setup file. It does not generate a drill file as part of the CAM job. You need to run excellon.cam separately and add that file to the rest of the CAM files to have a board made.

    • The gerbers should end up in the same directory that your .SCH and .BRD design files live in. The CAM Processer window should list a directory in the bottom-left corner - that should be your project directory, and it should be where the gerber files get saved to.

  • May sound like a dumb question, but wouldn't the Atmega 328 need a external crystal? If not, does this design work or is it purely a demonstration?

  • Hi! I'm trying to upload my design to OSH Park. It looks like the SparkFun CAM file that is used does not include a GKO file that OSH Park requires. It needs an outline of the board. Which layer should be used to do this? Thanks!
