Adafruit IS31FL3741 13x9 PWM RGB LED Matrix Driver - STEMMA QT / Qwiic

Add a splash of RGB LEDs to your project with this 13x9 RGB LED matrix breakout featuring 117 RGB LEDs arranged in a 13x9 grid.

Each LED is 2x2mm with 3mm pitch spacing. The matrix uses the ISSI IS31FL3741 controller chip to handle PWM for 24-bit color via I2C communication.

• Large controller chip handling PWM instead of smart LEDs
• Adjustable current driver for brightness without losing color resolution
• Runs on 3.3-5V power and logic; 5V recommended for optimal green and blue LED brightness
• Multiplexed matrix with maximum 40mA per cathode driver
• Board includes four mounting holes and is tiled for side-to-side chaining of up to 4 boards
• Compatible with STEMMA QT and SparkFun Qwiic connectors for solderless connection
• Use Arduino or CircuitPython/Python libraries to control LEDs

This board is excellent for small displays with simple animations and is ideal for projects that require customizable RGB LED matrices with easy I2C connectivity.
