Single Sided Really Bare Bones Board Arduino in EAGLE.

Paul Badger of Modern Device Company designed the "Really Bare Bones Board" (http://moderndevice.com/RBBB_revB.shtml) and placed the design in the public domain. (Thanks Paul!)

I've converted the design to the EAGLE CAD package, and in the process I noticed that you can pretty much make it into a single-sides board as well, probably not to hard to make using hobbyist materials.

Hi
How do I find the physical board size in Eagle?
Or can you tell me the physical outside dimensions please.
I am looking to get some made.

In the board editor, you can use the "info" command on the lines in the board outline. The SSRBBB is slightly less than 18x78mm

This board kind of reminds me of SolarBotics' Ardweeny, except IT'S DIY!!!!

Um instead of using the AtMega 168 can you just substitute the 328 without any changes to the design? And can you substitute the resonator with this crystal?

Thanks in advance :)

Yes, the 328 will drop in with no modifications. If you want to use a crystal, you'll need to also find room for the two 22pF caps that go with the crystal (these are built in to the resonator.) A couple of tiny SMT caps would go on fine, but it would be difficult to find room for more TH components.

Ok thanks for the quick reply i was just trying to save some $$$ by using a cheap crystal. Thanks for your help. If i wanted to could I just solder the 22pF caps onto the leads of the crystal? Thanks for your help again :)

A crystal, while more accurate, is not used on the RBBB for cost reasons. Resonators are usually a *lot* cheaper. Unless you go to your local Radio Scam.

While it is conventional wisdom that resonators are cheaper, I seem to find this to be not very true, at least in small to moderate quantities. Both 16MHz resonators and "typical" crystals are about $0.30 from Mouser, for instance. I like resonators because they're smaller and included the needed caps in the same package, making PCB layout and assembly easier.

please update the link to the files. I have been looking for this as I will be using my makerbot to mill pcbs and really want to make this.

Ah; I had tried to correct the link before, but something went wrong. It should work now.

It is down again. Any chance you can re-upload it somewhere?

Grr. Stupid "permanent" sites that aren't! Now at Google Docs

Can someone update the link to the files perhaps to somewhere safer than geocities? Thaks!

This deserves a whole lot of love! Is the pin spacing 0.1 inch on the board meaning you can use in a breadboard? The 7805 option, the two 100n caps for noise reduction, single sided......this is pure win on every level!

nice :) will have to give this a try and see if it can be done with the sharpie method XD (i have no way to tone transfer)

Very much kudos. Single sided designs can be hard! I'll definitely be using this next time I need an arduino without in-built 232/USB - at the moment I'm making a full size board and just not populating the comms parts.
