SLIDE Hardware Requirements
Thought for 10 sec
I’ll treat the primary mechanical placements as locked, audit the board for overlaps, off-board parts, orientation issues, decoupling/support-part placement, and unrouted readiness, then clean up only the small components. I’ll leave the power-switch area flexible and won’t route yet.
Worked for 13 mins 55 sec
Small-part placement and silkscreen cleanup are complete, but the audit found real pre-routing blockers: incomplete U2/U3/U4 power wiring and an exposed-pad conflict in U2’s footprint. I’m fixing those electrical issues now while keeping every locked primary location unchanged.
Worked for 47 sec
Small-component placement and silkscreen cleanup are complete, with all primary/mechanical components held fixed. No routing or copper was added.
Remaining before routing
- Fix incomplete U2/U3/U4 power circuitry; currently 45 ERC floating-pin errors.
- Resolve five U2 exposed-pad/footprint net conflicts.
- Decide how to handle J1 shell pads extending beyond the board.
- Finalize SW3 placement.
- Re-run DRC/ERC and routing-congestion checks; 96 airwires are expected before routing.
Execution stopped because no ACUs remain.

SLIDE Rev A — Dimensioned Placement Review (Approval Stage)
Scope: placement/mechanical approval only. No routing was performed.
Datum and board
- Coordinate system: front/top view; board center = (0,0); +X right; +Y toward enclosure top/front.
- Enclosure outside: 87.5 × 84.0 mm.
- PCB outline retained/confirmed: 81.9 × 78.4 mm, 2.0 mm corner radius. This leaves nominal enclosure-side clearance of 2.8 mm per side before wall draft/tolerance and is a reasonable internal-board envelope for typical 2–2.5 mm walls plus boss clearance.
- Board edges: X = ±40.95 mm; Y = ±39.20 mm.
- Stackup read-back: four copper layers (Top, Mid-Layer 1, Mid-Layer 2, Bottom), 1.6 mm-class standard construction. Mid-layer intent is ground/power reference; preserve this through routing.

Fader geometry
- Visible cap: 9.0 × 14.5 mm.
- Required outside edge span, cap 1 to cap 4: 46.0 mm.
- Therefore first-to-fourth center span = 46.0 − 9.0 = 37.0 mm.
- Equal pitch = 37.0 / 3 = 12.333333 mm.
- Recorded centers satisfy this: −32.2500, −19.9167, −7.5833, +4.7500 mm.
- Blocking footprint issue: the current PTA4543-2010CPB103 layout body is about 13.05 × 62.3 mm and its origin is not proven to be the cap/shaft center. The 45 mm travel and cap-center datum therefore cannot be approved from this footprint. The four footprints extend beyond the 78.4 mm PCB envelope. A manufacturer drawing or corrected footprint with explicit cap-center datum is required before enclosure-slot approval.
OLED drawing derivation
Primary source: Raystar REA012832PWAP3N00000 contour drawing.
- Module PCB: 60.0 × 18.75 mm nominal.
- Active area: 42.22 × 10.54 mm.
- Drawing-derived AA offsets from module edges: left 2.25 mm, right 15.53 mm, top 4.50 mm, bottom 3.71 mm. The AA is not centered on the module PCB.
- Horizontal center offset: AA center = 2.25 + 42.22/2 = 23.36 mm from module left; module center = 30.00 mm; therefore AA center is 6.64 mm left of module PCB center.
- Vertical center offset: AA center is 0.395 mm below the module PCB center in the drawing orientation.
- Lower-left opening target retained as AA center (-13.75, -28.25) mm. Derived module PCB center is therefore (-7.11, -27.855) mm, preserving the required rightward PCB overhang.
- Header: 7 pins, 2.54 mm pitch; drawing calls out approximately Ø1.0 PTH / Ø1.8 pad and pins GND, VCC, D0, D1, RES#, D/C#, CS#.
- Blocker: the project still contains only J6, a generic 1×7 header. The exact Raystar footprint is not in the Flux library, and standalone review graphics could not be retained on a valid non-copper layer. Do not approve enclosure bosses, module holes, or connector clearance until an imported/custom Raystar footprint is bound to J6 and checked against the drawing.
Capture switch
- Added SW4: Kailh Choc low profile PG1350 and placed at (26,-22) mm beneath the lower-right 14.75 mm square visible keycap target.
- Official Kailh PG1350 documentation was located and includes a recommended PCB layout; the Flux footprint has the expected two electrical pads plus mechanical holes and a 19.05 mm key-spacing envelope.
- Risk: the library part lacks attached datasheet metadata, and exact pad/hole coordinates were not exposed in layout read-back. Treat this as a provisional datasheet-cross-checked footprint, not final manufacturing approval. SW4 pins are intentionally no-connect for this placement-only stage; assign a GPIO/GND net before schematic approval.
Speaker, antenna, battery and rear-interface interference
- Speaker reserve: 40 × 20 mm, upper-right; use bounds X=20..40 mm, Y=-6.25..33.75 mm for the chosen orientation. No speaker mounting holes are assumed.
- Grille target: five slots in an envelope approximately 14.75 mm wide × 45 mm tall, centered on the speaker. This is an enclosure feature, not a PCB drilling pattern.
- J4 remains the 2-pin speaker connector.
- U1 right-edge attempt does not pass: its body bounds extend to X≈48.8 mm while board edge is X=40.95 mm, and it overlaps the speaker reserve/power/audio cluster. An antenna overhang requires an explicit all-layer no-copper region beneath the antenna; none is yet authored.
- Battery reserve used for interference review: X=-30.5..14.5 mm, Y=-21..9 mm. Keep tall components and the antenna out of this volume.
- Rear connectors remain grouped at Y=-39.2 mm. The current USB-C model is unusually large (31.15 × 42.59 mm), and the two SJ2-3593D jack bodies are 20.6 mm wide; the present center spacings cause physical/courtyard overlap. Rear panel order is practical, but connector centers must be re-spaced or narrower/right-angle parts selected.
Verification and approval status
- Four-copper-layer stackup verified by direct stackup read-back.
- Board outline verified at 81.9 × 78.4 mm.
- Fader pitch arithmetic and stored center coordinates verified.
- Four existing 2.2 mm NPTH mounting-hole layout pads verified; duplicate additions were removed.
- PG1350 capture footprint added and centered in the requested lower-right region.
- No routing was started.
- Placement review still reports overlapping copper/component bodies and extreme density; the aggregate top-side footprint area exceeds board area, mainly because mechanical footprints/envelopes are invalid or mutually conflicting.
Enclosure-change recommendations before placement approval
- Obtain/approve the exact 45 mm fader drawing and rebuild the footprint around the cap center datum; do not move enclosure slots to match the present 62.3 mm footprint.
- Import/create the exact Raystar module footprint including its two mounting holes, 7-pin row, board outline, and AA courtyard; then center the AA at (-13.75,-28.25) mm.
- Confirm PG1350 soldered-switch variant and compare every drill/pad coordinate with Kailh CPG135001 drawing before release.
- Increase rear-panel connector spacing, stagger connector depth, or select narrower jack footprints. Do not cut the rear panel from current centers.
- Move the ESP32 antenna to a genuinely clear edge/corner, and add an all-layer copper/component keepout under and ahead of the antenna. The enclosure should use RF-transparent material in that zone.
- If the 87.5 × 84 mm enclosure must remain fixed, consider a second small UI/display PCB or a taller two-board stack. The present single-board mechanical set is not placement-approvable without corrected fader/OLED footprints and rear-connector changes.
