This compact 8×8 yellow-green LED matrix packs 64 ultra-bright LEDs into a 1.2" square footprint. With 0.1"-spaced pins on each side, it plugs directly into a breadboard — one row per side — making it easy to prototype scrolling signs, animations, and small displays without any additional hardware mounts.
The matrix uses a common multiplexed grid arrangement and requires 1:8 multiplex control. Drive it with a 74HC595 and TPIC6B595 shift register pair, or simplify your wiring with a single MAX7219 LED driver IC, which handles all the multiplexing for you.
Key Features
- Resolution – 8×8 grid (64 LEDs total)
- Colour – Ultra-bright yellow-green
- Size – 1.2" (approx. 30mm) per side
- Pin Pitch – 0.1" (2.54mm) — standard breadboard compatible
- Pins – 16 total (8 per side)
- Drive Method – 1:8 multiplexed (requires shift registers or a driver IC)
- Part Number – KWM-30881CUGB
Ideal For
- Scrolling text and sign displays
- Animation and pixel art projects
- Arduino and microcontroller display experiments
- Learning LED matrix multiplexing techniques

Jargon buster
Plain-language definitions for the technical terms used above.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- LED driver
- An LED driver is a control chip or circuit that supplies and switches power to LEDs. For a display board, it reduces the number of microcontroller pins needed and handles tasks like lighting the right segments and adjusting brightness.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
