I have an Odyssey X86J4105. Below are some links for anyone interested. It has an onboard ATSAMD21G18 (like Arduino Zero). I can’t find any Eagle CAD footprints/parts for it online and I’m very slow at building custom parts. Is anyone interested in drawing one for me and making it available to the public? There is a 3D file available for it but otherwise I may have to measure it for you.
