Kits
A project's full parts list, boxed, with assembly notes and its license.
How we source
Substitutions explained
When a part is out of stock you see the alternative and exactly what changes, before it reaches your order.
Licenses stay attached
Each kit states its hardware license and what it allows for a derivative, a classroom, or a small run.
