Just wanted to make sure we recognize all the work @RebelMike and @Essen have made creating this Run's CoB Now with:

More sane orientation
Pin 1 Fiducial
Overall better routing and yield improvements
Anti-reverse element there is a hole you can add a pin header to ensure CoB orienation Thanks guys!

@everyone who ordered bare die from wafer.space Run #2 should have gotten a fedex tracking confirmation message yesterday for the shipment of the first ~200 bare die. If you haven't and think you should have, please poke me via email at tim@wafer.space I'm excited to see people bring up their projects! You can find out more about the various projects on Run #2 on the new pages @ https://wafer.space/ws-run2/
