README
hardware/two-layer/sandwich/panel/README.mdFour-board quotation panel
One 238 × 114 mm, two-layer panel contains one Lower, Upper, Wheel and Encoder board. Five panels provide five complete sets. The individual board outlines, component positions and copper are preserved by translation; nets are isolated between boards. The panel uses 2 mm routed gaps, 5 mm tabs and 0.6 mm mousebites on 0.9 mm pitch. The drill row lies outside each finished board outline.
Upload MagMouse-panel-gerbers.zip as Panel by Customer, 4 designs,
5 panels, FR4, 1.6 mm, 1 oz, green/white, ENIG 1 µin, 0.30 mm minimum via
drill and tented vias. Components, assembly and stencil are separate.
panelize.py generates this folder from the four individual boards and checks
exact translated pads, traces, drills and filled copper; connected substrate;
router access; and native KiCad DRC. panel-manifest.json records source hashes.
The individual boards also pass ERC, DRC and schematic parity checks, with zero
unconnected nets and zero via-hole/SMD-pad intersections.
This is a quotation package. Supplier CAM approval and prototype electrical, thermal and enclosure-fit checks remain necessary before production release.

Questions
How big is the Wheel PCB?
It measures 70 × 67 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Wheel use?
87 parts, built around the SN74LVC125APWR-TP, ADS7038IRTER, DRV8316RRGFR and SN74LVC08APWR-TP. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Wheel KiCad files?
From the sbarisic/MagMouse repository on GitHub, at the commit this page was made from: the board is hardware/two-layer/sandwich/wheel/Wheel.kicad_pcb and its schematic hardware/two-layer/encoder/Encoder.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Wheel design in my own project?
Its repository states no licence, so its author keeps all rights: ask sbarisic before reusing the design.
