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?
Could be using the internal oscillator (8Mhz) :)
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!
You would typically use the Dimension layer for board outlines. I'm pretty sure OSH Park have a CAM file available, though the one I found in a quick search seems outdated, so you may have better success with http://diezc.com/2013/05/23/oshpark-gerber-cam-job-eagle/.
Note that you can also send them Eagle files directly :)
