I am not well-equipped to sort thousands of tiny parts at home. I have therefore prepared this parts list with links to the appropriate pages on the suppliers' websites. If you bought a board-only kit, this page is for you. Most of these parts are from Mouser. One kind of chip I found only at Digikey. Headers and related items are best found at Jameco. Most parts may be substituted for equivalents. Ones that cannot be substituted are marked.
To speed things up, here is a Shared Project. from my account at Mouser. Click that and all the parts you need from Mouser are selected for you. Delete what you already have, don't want, or would rather do differently.
