Checked against the drawing
Every breakout board is measured and its pinout checked against the maker's drawing before it goes on the shelf.
Open-source hardware, every part in one box.
Pick a build from the open hardware community. We match its bill of materials to parts we stock and check by hand, then ship the whole list together.

Ranked by documentation, community and how easy the parts are to get. Each entry tells you whether to buy a kit, a parts list, or a mix.
Bring your own bill of materials.
Paste a parts list, drop in a CSV, or upload a KiCad export. Every line is matched to stock, and anything we are unsure about is flagged, so nothing gets swapped without your say.

Kits
Everything a build needs, bagged and labelled, with assembly notes and the project license in the box.
How we source
Substitutions explained
If a part runs out, we show you the replacement and exactly what differs before anything changes in your order.
Licenses stay attached
Each kit names its hardware license and what it allows, whether you are remixing it, teaching with it, or building a small batch.
