## V2 rework — silkscreen & mechanical (added 2026-08-28)
|
||||
|
||||
Cosmetic/mechanical items for the in-progress V2 rework (EEPROM→93LC56B,
|
||||
reverse-mount LEDs, J3 slot already done). These are PCB-layout tasks, not
|
||||
schematic changes.
|
||||
|
||||
- [ ] **1. Add the project name in silkscreen.** Put a "re-bba-rb" (or chosen
|
||||
project name/version) label on the board silkscreen so the assembled board
|
||||
is identifiable. Pick a copper-free spot; watch the JLC 1.0 mm min text
|
||||
height / 0.15 mm min line-width floor (same rule that just caught the LED
|
||||
refdes). Consider adding a small rev tag (e.g. "v2") next to it.
|
||||
- [ ] **2. Extend the board out to the ethernet socket so it sits flush with the
|
||||
GC.** Lengthen the board outline (Edge.Cuts) toward the RJ45/magjack (J2)
|
||||
end so the finished board reaches flush with the GameCube's shell instead
|
||||
of stopping short. Mechanical-only (move the board edge + any ground pour
|
||||
to suit); keep the SP1/J3 edge geometry fixed. Verify the new outline
|
||||
against the GC slot depth before ordering.
|
||||
- [ ] **3. Add back-side silkscreen legends for the LEDs.** Label what each LED
|
||||
means on **B.SilkS** (the back is the viewing side — reverse-mount LEDs
|
||||
emit through the board, top faces into the GC slot). Map from the current
|
||||
build: LEDG/D6 = heartbeat, LEDR/D7 = EXI activity, RGB D11 = rx / D12 =
|
||||
tx / D13 = ready, D8/D9 = USB/GC power handover indicators. Confirm the
|
||||
final per-LED meaning against `synth.py` + BRINGUP.md before lettering, and
|
||||
mind the same silk text-height/width floor as item 1.

||||

||||
