It has been a challenge, but we finally managed to complete the Rhino layout; thanks to a great effort by the team. The board ended up with 14 layers, a few more than we originally anticipated, but that is to be expected when most of the routes were targeted impedance, length matched and differential. All the latest Altium design files have been uploaded
to the Rhino svn repository (http://svn.ohwr.org/rhino-hardware-01). If you have the time please review and send to us feedback by the end of Monday, November 15th.
