BrandKoshi Electronics

The Pixel LED Rainbow Matrix DIY Kit from Koshi Electronics gives you everything you need to build your own dazzling RGB rainbow pixel matrix — flowing colours, chasing patterns and animations — at a lower price. It comes without a base board or backing sheet, so it’s compact, cheaper and safe to courier. You simply stick the strips onto any flat surface you like — wall, glass, mica or plywood. Perfect for a Ganpati, mandap or stage backdrop.

What’s Included

  • SK6812 RGB pixel LED strips — the same premium pixels as our ready-made set
  • HD pixel controller with the latest high-quality effects
  • 5V slim-body SMPS power supply
  • Connecting wires and everything needed to assemble the matrix

Not included: the base board and the back adhesive/sticking sheet — you fix the strips onto your own surface. This is exactly what keeps the kit cheaper, smaller and easy to ship.

Stick It On Any Surface

There’s no fixed board, so you can mount your matrix wherever you want. The strips stick neatly onto:

  • Directly on a wall
  • Glass
  • Mica sheet
  • Plywood or any flat board / frame

Why Choose the DIY Kit?

  • Lower price: no board or backing sheet means it costs less than the ready-made set.
  • Compact & ship-safe: a big rigid board is bulky, costly and easily damaged in transit — this kit ships small and safe.
  • Your choice of surface: build it exactly the way and size you want, on the material you prefer.
  • Same stunning result: identical SK6812 pixels, controller and effects as the ready-made rainbow set.

Sizes

Kit Pixel Matrix Display Size
12×24 12 columns × 24 rows (~288 pixels) 2×2 foot
24×24 24 columns × 24 rows (~576 pixels) 3×3 foot

Note: 12×24 and 24×24 are the pixel matrix (columns × rows), not feet. 2×2 ft = 12×24 matrix, 3×3 ft = 24×24 matrix.
