I went and looked at the pictures, but I could not get a sense of the size difference between boards. Is there an appreciable size difference? Jim Hi Jim! Thanks! Yes, there is a size difference. The N8VEM PCBs are Eurocard 160x100 mm standard. The mini-N8VEM is slightly larger about a centimeter or so larger on length and width. It won't fit in a Eurocard rack but is still small enough to work fine as a stand alone SBC. It will also plug into the N8VEM ECB backplane. There is a lot of information available on the wiki and you may want to consider asking questions on the mailing list. All the files for mini-N8VEM SBC are available in the Eagle format including schematics and PCB layout. If you want anything else just ask and its probably available. Thanks and have a nice day!
