I just tried to route all the races without overlaps. I didn’t really look at the other design rules, like trace width or drill size. I tidied up the components a little, then used the draw tool on the (20) Dimension layer to set up the outline of the board.
Sounds promising! So I pressed it, and ended up with a board like this:ĭifferent colours represent different layers of the board, so it looks like some of my traces are being routed on the bottom (blue lines) and some on the top (red lines). I switched to board view, arranged the components to be roughly placed as on the reference board, then found a button labelled Autorouter. Again, not sure of the package size, so I’m starting with a RESONATOR-SMD-4.5X2.0 (Version 1) package.
Maybe this is intended to be a resonator(?) so that’s what I’m using for now. On the board diagram the crystal has 3 connections, but in the Sparkfun library, they all have 2. Hopefully this won’t make a difference.Īnd I see that the ISP headers (in the Sparkfun libraries) also come in a variety of packages, and I’m not sure which one is appropriate. I notice that the pins on my J2 FTDI are labelled slightly differently (RTS vs DTR). I found this chart to help try to figure out which size we’re using: Then I populated my schematic with parts, based on the reference diagram: I downloaded some libraries of components, mostly from Sparkfun, I also downloaded some specific libraries for the ATTiny processors. Can you guess what you click on to add things to your empty schematic?Īnyway, I figured out the mystery meat navigation slowly.

It’s got a pretty awful UI, like a Windows app -).
