THE MANUAL LIBRARY
The kit’s own booklets, generated from the same modules the bench runs on: every level’s projects, every mission’s chapters and the whole classroom course, as A5 spreads you can read in the browser or download as a PDF. Each build carries its parts, its wiring and its schematic, and opens wired on the bench in one click.
