Sixteen addressable RGB LEDs on a 1-inch square
The ET-D06 is built around the 16 × WS2812B-2020 (2×2mm) addressable RGB, 24-bit colour, 800kHz. It runs from 5V; up to 0.19A at full white (≈12mA per LED channel × 3).
Designed in Dubai by ElectroTrical — the full schematic, BOM and design notes are published below.
Good for
- Tiny pixel art
- Indicator panels
- Light-up buttons
