Have you always wanted to upgrade your ensemble with a creepy-cool creature PCB silkscreen and an eye-blistering arrangement of LEDs? We love to put NeoPixels on our face, as evidenced by our many glowy LED glasses projects. Each of these requires quite a bit of soldering, and the cost of each NeoPixel adds up quickly. So we wanted to make a PCB assembly that can be used by any microcontroller to make glamorous face-tronics.
Please note: You get one LED Glasses panel per order. The silkscreen selection is random per order; we can't change or control which one you get!
The Adafruit LED Glasses Front Panel has 116 artfully arranged 2x2mm RGB LEDs, all controlled with an IS31FL3741 I2C Driver that handles all the PWMing, so it's plug-and-play with almost any microcontroller.
On each side are STEMMA QT / JST-SH plugs - use these with one of our cables to attach it to your driver board of choice. Of course, you can pick left or right, then if you want to add on more hardware, like an accelerometer or light sensor, you can chain onto the other side. There's also six mounting holes for attaching to a glasses frame of your choosing - we recommend getting some 'fashion frames' from the mall or a street vendor, they're all the style and will provide a great mechanical support.
We have four different silkscreen designs: Bug, Wolf, Cat, and Dragon (peep those fearsome fangs!) Each design is exactly the same mechanically and electrically, the only difference is what is silkscreened on top of the PCB.

Gaze upon these features:
IS31Fl3741 LED driver chip uses I2C to control the LEDs with 8-bit PWM per color (24-bit per RGB LED), write pixel data and it will handle the matrix driving automatically.
Power and communicate over STEMMA QT for easy wiring
The LEDs are arranged as 2 x 24-LED rings around each eye and an overlapping 16x5 matrix. The matrix has two bottom pixels 'missing' over the nose. Some LEDs are shared between both matrix and rings!
