Your assembly guide is not lost. Every build guide we publish is free and online, so you can pick up where you left off.
They are all on our resources page. Find your kit there and you get the full step-by-step build guide, and for most kits the usage guide and the coding tutorials as well.
All our projects are open source, so the schematics, code and documentation are on our GitHub too.
If you cannot find the guide for your kit, message us here, or email [email protected], with the kit name and we will send you a direct link.
