  • 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, 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 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!
