Child Safe RGB Badge


I’ll remove the per-LED WS2812B decoupling capacitors that were added despite the V6 datasheet feature note, then re-run checks and update the safety/power notes accordingly.
Removed C24–C43, the per-LED WS2812B-2020-V6 capacitors, and kept the shared LED-rail bulk capacitor C5. Re-ran checks: no open ERC/passive warnings found.
Updated:
J1 need PCB cutout, replace it with TYPE-C 16PIN 2MD(073)
I’ll replace J1 with the requested TYPE-C 16PIN 2MD(073), first finding the exact library part and preserving the existing USB-C nets, then I’ll verify the connector pins/checks afterward.
Replaced J1 with TYPE-C 16PIN 2MD(073) (LCSC C2765186) and restored the existing power-only USB-C wiring:
  • VBUS pins → VBUS_RAW
  • GND + shell pins → GND
  • CC1/CC2 → existing CC pulldown/ESD nets
  • DP/DN/SBU pins marked no-connect
Verified J1 schematic connectivity and ran targeted ERC/DRC checks; no J1-related open issues were reported.
Verify connector and layout
Place J1 at edge
Run full DRC
Verify cutout geometry
