## Description

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. Key Features 9×16 LED Grid – 144 individually addressable yellow LEDs Charlieplexed Design – Efficient wiring for maximum LED density IS31FL3731 Compatible – Designed to work with the Adafruit 16×9 Charlieplexed PWM LED Matrix Driver PWM Control – Smooth brightness control on each LED via the driver Ideal For Scrolling text displays and message boards LED animations and visual effects projects Wearable electronics and cosplay builds Status indicators and data visualisation Package Contents 1× Adafruit 9×16 Charlieplexed LED Matrix – Yellow Note: This is the LED matrix only.
