After submitting the 105c version to the DorkbotPDX PCB order, I mentioned I'd make one at home, but the traces looked so thin on paper and I didn't like the routing of gnd to the crystal area, so I made a few changes to optimize it for toner transfer and home etching.
Here's a shared folder with the updated, v107 EAGLE files and a 600dpi jpeg for toner transfer. See the low res at right, or click for higher res; get the full res jpeg here.
Love it! My only issue is that (as has happened many times) I can't get the ground plane fill to show / print in Eagle. I've tried all the silly workarounds I know short of filling it in in Photoshop.
ReplyDeleteI've made a few changes (only bringing out a few of the pins for instance) in order to turn this into a standalone / smaller board, and I hope to get it all up and running!
Rats nest should resolve and draw in the plane, it doesn't load up filled for some reason, strange...
ReplyDeleteThe resistor at pin 13 should be removed/ shorted if you want that LED to work. Nice design!
