A module-level wiring viewer for the user-following smart cart. This is NOT a PCB layout or a cart-control application. The project contains original textured vector illustrations, an accurate reference breadboard contact map, terminal data, and editable electrical schematic expo
A module-level wiring viewer for the user-following smart cart. This is NOT a PCB layout or a cart-control application. The project contains original textured vector illustrations, an accurate reference breadboard contact map, terminal data, and editable electrical schematic exports.
The first three drawings use named functional terminals and cable bundles; their pictorial geometry is not a mechanical drawing or exact purchased-board pin placement. Follow physical terminal names and the contact tables, not illustrative silkscreen positions. Components with unknown specifications and fuse…
