Building 16x16 LED Matrix
Thought for 1 min 35 sec
54 days
I found a WS2812B library part and JST-PH 3-pin connectors; for protection I’m using a PCB blade-fuse holder rather than a 20 A PPTC to avoid excessive voltage drop/heating at LED-matrix currents.
Worked for 18 sec
54 days
I’m adding the 256 LEDs now as a single cascaded data chain, with shared 5 V/GND rails and entry/exit connectors.
Worked for 6 mins 46 sec
54 days
I’m blocked because the account has no available ACUs, so I can’t continue tool execution.
Accomplished so far:
- Renamed the project to 16x16 WS2812 Matrix and updated its description.
- Added the main schematic components: 256× WS2812B LEDs, 260 capacitors including per-pixel decoupling and bulk input caps, screw-terminal power input, JST data in/out connectors, 330 Ω data resistor, and a blade fuse holder for 20 A protection.
- Wired the main power-entry path, fuse, bulk capacitors, JST data connectors, and first/last data endpoints.
Remaining work:
- Finish wiring all 256 WS2812B VDD/GND pins and the full DOUT→DIN cascade.
- Add project documentation / power budget notes.
- Run ERC/design review and fix any issues.

You can choose between polarized and non-polarized types, its symbol and the footprint will automatically adapt based on your selection. Supported options include standard SMD sizes for ceramic capacitors (e.g., 0402, 0603, 0805), SMD sizes for aluminum electrolytic capacitors, and through-hole footprints for polarized capacitors. Save precious design time by seamlessly add more information to this part (value, footprint, etc.) as it becomes available.
