The Adafruit LED Charlieplexed Matrix is a 9×16 grid of yellow LEDs arranged in a Charlieplexed configuration. Designed to pair with the IS31FL3731 LED matrix driver, this display lets you create scrolling text, animations, and visual effects with individually controllable LEDs.
This is a bare LED matrix only — no driver chip or resistors are included. You'll need a compatible IS31FL3731 breakout board to control the display. The Charlieplexed design keeps wiring simple while maximising the number of LEDs you can drive.

Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
