Building 16x16 LED Matrix
Thought for 1 min 35 sec
51 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
51 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
51 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.
