=== Bill Of Materials ===

For GenBoard v3.x there is no "official" BOM. If you really want to assemble yourself, see the schematic and maybe generate the BOM yourself. But you'll have hard time getting some of the components, especially if you want one or two. Easier and cheaper to get a mintested board (see GenBoard/VerThree/Testing) from the WebShop. Why not spend your time on planning (drawing, writing, eg. on a wiki page from MembersPage) your engine-modifications? If you come up with nice descriptions and drawings (maybe photos) of how GenBoard fits/will fit into your application, you'll get a contributor's discount, which means you get the board for less than you could just get the components in small quantities - with much hunting.

GenBoard/VerTwo BOM - nothing more than history

This is old information, for GenBoard v2.2.
