V3 boards came in...

A project log for CAN Bus Arduino Clone

So last night the newest version of the boards finally arrived. I was so excited I started populating them right away. I got about 80% done before I realized there where not traces visible. :/ Hoping it was manufactured in a way that the traces where on the internal layers I broke out the DMM to check continuity... Nope, just no traces.

Still working to figure out what went wrong but version 3.1 looks promissing.

Look at the bright side: You discovered the error before applying power.  

Most painful example I've seen:  Grad student sends his chip design off to MOSIS.  Gets it back later, and discovers a typo in the metal layer shorts power to ground.  He'd made a $10,000 batch of fuses.

Ever consider using the 32 bit boards with CAN built in?

Yeah, glad you can find the humor in it. OSH park has been great and I think we found the problem. Maybe Eagles backup/versioning and I sent them unrouted brd files. anyway I'm getting a new board spun up, hopefully all goes well

LOL, I've done stuff like this. Thanks for the laugh!

It's delightful to know that I'm not the only one capable of making mistakes here. :D 

Thanks for sharing.
