16 by 16 centimetre square flexible black FPCB with 256 individually addressable 5050SMD LEDs in alloy wiring

KEHIPI

KEHIPI WS2812B 16x16 256 LED Matrix Flexible FPCB DC5V

SKU CH-A4NM-33AD1

A 16×16 flexible matrix of 256 individually addressable WS2812B LEDs on black FPCB for custom text, graphics and animation at DC5V

  • MaterialPlastic
  • Individually addressable WS2812B ICs enable custom pixel art and scrolling text
  • Flexible FPCB substrate bends to curved surfaces while preserving pixel integrity
  • Works with Arduino, Raspberry Pi, WLED, SP802E and SP530E controllers
  • Chainable 3-pin JST connectors allow modular expansion to larger displays
  • 256 LEDs at 5 V draw 0.1 W to 0.3 W per LED depending on colour mix

16×16 Addressable LED Matrix

The KEHIPI WS2812B panel packs 256 individually addressable 5050SMD pixels onto a 16 cm square of flexible black FPCB. Each LED contains its own WS2812B driver IC and accepts GRB colour order at 24-bit depth. The sheet draws DC5V only and consumes roughly 0.1 W per LED for a single colour up to 0.3 W per LED at full white.

Makers, Not Installers

Hobbyists building scrolling text, pixel art or music-reactive displays with Arduino, Raspberry Pi, FastLED, WLED or SP802E/SP530E controllers will find the 3-pin JST chainable design straightforward. The IP30 rating and alloy-wire construction mean the panel is not suited for outdoor, damp or high-vibration mounting, nor for buyers who need waterproofing or gold-bond reliability.

256 Pixels, 25–75 W Headroom

A 50 W (10 A) supply runs typical patterns comfortably, while a 100 W (20 A) unit covers sustained white output across all 256 pixels. Continuous full-white illumination pushes the alloy wiring to its thermal limit and shortens LED life, so brightness should be capped below maximum for long sessions. The matrix operates from –20 °C to +50 °C and bends to follow curved surfaces without breaking pixel integrity.

Questions about this item

What controller and power supply do I need to run this 256-pixel WS2812B matrix?

Use a compatible controller such as WLED, SP802E or an Arduino with FastLED, and feed the panel with a DC 5 V supply rated at 10 A (50 W) or 20 A (100 W) — never apply 12 V or 24 V.

Can I chain this 16 cm × 16 cm panel to an older WS2812B strip I already own?

Yes, the 3-pin JST connectors and identical WS2812B protocol let you daisy-chain the matrix to existing strips; just match data direction, share a common ground and size the 5 V supply for the combined 0.1–0.3 W per LED draw.

How do I confirm the matrix is wired correctly after powering it up?

Upload a simple colour-wipe sketch (red, then green, then blue) — each of the 256 LEDs should sequence cleanly at the 120° viewing angle with no flicker; if colours swap, adjust the GRB order in your code.
