The Adafruit LED Glasses Front Panel features 116 artfully arranged 2×2 mm RGB LEDs controlled by an IS31FL3741 I2C driver chip. Simply connect it via STEMMA QT to your favourite microcontroller and start creating dazzling face-mounted light displays — no complex wiring or individual LED soldering required.
The LEDs are arranged as two 24-LED rings around each eye and an overlapping 16×5 matrix, giving you flexible control for animations, patterns, and colour effects. Pair it with the Adafruit LED Glasses Driver for a compact Bluetooth-enabled setup, or use any I2C-capable microcontroller.
Key Features
- 116 RGB LEDs – 2×2 mm LEDs with 8-bit PWM per colour (24-bit colour per LED) via the IS31FL3741 driver
- I2C Control – Write pixel data over I2C and the driver handles all matrix driving automatically
- Dual STEMMA QT Ports – Connect to your driver board on one side and daisy-chain additional sensors on the other
- Flexible LED Layout – Two 24-LED eye rings plus a 16×5 matrix with some shared LEDs between both
- Six Mounting Holes – Attach to fashion frames or custom glasses builds
- Four Silkscreen Designs – Bug, Wolf, Cat, and Dragon (randomly selected per order)
Ideal For
- Wearable LED glasses and face-mounted displays
- Cosplay and costume lighting effects
- Interactive art installations and performances
- Eye-catching conference and event accessories
Package Contents
- 1× Adafruit LED Glasses Front Panel (silkscreen design is randomly selected)
Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- 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.
- 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.
- 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.
- RGB
- Short for red, green and blue, usually referring to an LED that can mix those three colours. It matters because controlling an RGB LED teaches how separate outputs combine to create different colours.
- STEMMA
- A plug-and-cable connection system used on some maker electronics boards to make wiring simpler. If a product uses STEMMA, you need the matching cable or connector type to plug it in without soldering.
- STEMMA QT
- A small plug-in connector system for I2C boards that lets you connect compatible sensors and controllers without soldering. It matters because it can make wiring faster and less error-prone, especially when adding several small modules to a project.
