Dual 16×16 LED matrix kit

This pack contains two flexible 16 cm × 16 cm panels, each with 256 individually addressable WS2812B LEDs on a black FPCB substrate. The matrices run on 5 V DC and draw between 25 W and 75 W per panel depending on the colour mix. Three-pin JST connectors allow the boards to be chained for larger displays. Suitable for makers building custom pixel art, scrolling text or music-reactive installations.

Makers who need affordable addressable grids

Hobbyists and experimenters looking for a low-cost way to add full-colour matrix lighting to Arduino, Raspberry Pi or WLED projects will find these panels practical. Buyers who require waterproof outdoor rating, gold-bond wiring or guaranteed all-white brightness at full power should look at other products. The IP30 rating and alloy-wire construction limit use to dry indoor environments and moderate white-level duty cycles.

5 V DC input with 0.1 W–0.3 W per LED

Each LED consumes 0.1 W for a single colour, 0.2 W for two colours and 0.3 W at full white, so a single 256-pixel panel can peak at 75 W. The supplier recommends a 5 V 10 A or 20 A supply and advises against sustained all-white output to protect wiring and LED longevity. This voltage and power profile is the key specification for selecting a compatible power source.

Questions about this item

What are the physical dimensions of each 16x16 LED matrix panel?

Each panel measures 16cm x 16cm x 0.2cm (6.3in x 6.3in) with a flexible FPCB substrate that conforms to curved surfaces.

How do you connect and power the matrices, and what common wiring mistake should be avoided?

Connect via 3-pin JST connectors for chainable expansion; power with DC5V only (10A/50W or 20A/100W supply). Never use DC12V or DC24V as it will damage the WS2812B ICs.

What long-term maintenance issues arise from running the matrices at full white brightness?

Running all LEDs at full white (0.3W/LED, 75W total) generates significant wire heat that reduces LED lifespan; avoid sustained all-white output to preserve longevity.
