README
hardware/cad/README.mdActive CAD: B.2 schematic / R.2 routing
Open B2/rack-atx-controller.kicad_pro for the controller schematic; B2/adapter.kicad_pro for the six-component passive adapter; B2/rack-atx-controller.kicad_pcb in PCB Editor for the 100×110 mm routed candidate. Routing was authorized by the user. No Gerber or CPL exists.
The B.2 controller contains 300 electrical components; the placement adds four M3 holes. The controller has 2,754 track segments and 185 vias; the 26×34 mm adapter has 30 segments and no vias. Both boards have zero native unconnected items and configured DRC violations. The web 3D uses native placement, copper and adapter coordinates with simplified component envelopes. USB/Ethernet qualification, factory DFM and physical tests remain; see ../ROUTING-R2.md. Generators write into B2/placement to preserve the routed master.

Export/ ERC operations on the same project must run sequentially. Source library paths in generators currently target macOS KiCad; adapt paths on other platforms.
BOM, schematic and PCB candidate footprints agree; custom TLP3122A and input-terminal land patterns live in RackATX.pretty, referenced relative to B2. Manufacturer/physical DFM qualification is still required. Raw CLI netlists stay ignored because they include workstation paths. Never publish them. Historical CAD in this directory and archive/B1 is retained, not the current revision.

Questions
How big is the Routing R1 PCB?
It measures 200 × 170 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Routing R1 use?
698 parts, built around the ESP32-S3FN8, B0505S-1WR3L, EL357N(B)(TA)-G and TLP3122A(TPL,E. 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 Routing R1 KiCad files?
From the ddasdkimo/rack-atx-controller repository on GitHub, at the commit this page was made from: the board is hardware/cad/routing-R1.kicad_pcb and its schematic hardware/archive/B1/cad/adapter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Routing R1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask ddasdkimo before reusing the design.
