## Description

The Adafruit IS31FL3741 RGB LED Matrix features 117 individually addressable RGB LEDs arranged in a 13×9 grid with 3 mm pitch spacing. Each 2×2 mm LED is driven by the ISSI IS31FL3741 controller chip over I2C, providing 8-bit PWM per colour channel for full 24-bit colour across the entire display. Unlike NeoPixel or DotStar LEDs, this matrix uses a single controller chip for all LEDs, with an adjustable global current driver for brightness control without losing colour resolution. The board supports 3.3V to 5V power and logic (5V recommended for best green and blue LED performance), and up to four boards can share one I2C bus for tiled displays. Key Features 117 RGB LEDs (13×9 Grid) – 2×2 mm LEDs with 3 mm pitch spacing IS31FL3741 Controller – I2C-driven with 8-bit PWM per channel (24-bit colour) Adjustable Global Current – Brighten or dim the entire display without losing colour resolution STEMMA QT / Qwiic Connectors – Solderless I2C connection with daisy-chain support 3.3V & 5V Compatible – Works with a wide range of microcontrollers (5V recommended) Tileable Design – Place boards side-by-side; address jumpers support up to 4 on one I2C bus Four Mounting Holes – Easy to secure in enclosures and projects Ideal For Compact RGB LED displays and status indicators Simple animations and colour patterns Wearable and portable LED projects I2C-based projects where simple wiring is preferred over HUB75 Package Contents 1× Adafruit IS31FL3741 13×9 RGB LED Matrix (assembled) Tip: I2C makes wiring simple, but pixel updates are slower than HUB75-style matrices. This display is ideal for small animations and status indicators — for video or large graphics, consider an HUB75 RGB matrix instead.
