Adafruit 15×7 CharliePlex LED Matrix FeatherWing – Warm White

You wont be able to look away from the mesmerizing patterns created by this Adafruit 15×7 CharliePlex LED Matrix Display FeatherWing. This 15×7 LED display can be paired with any of our Feather boards for a beautiful, bright grid of 105 charlieplexed LEDs. It even comes with a built-in charlieplex driver that is run over I2C.

We carry these FeatherWings in many vivid colorsthis is the Warm White matrix.

What is particularly nice about this Wing is the I2C LED driver chip has the ability to PWM each individual LED in a 15×7 grid so you can have beautiful LED lighting effects, without a lot of pin twiddling. Simply tell the chip which LED on the grid you want lit, and what brightness and it’s all taken care of for you. You get 8-bit (256 level) dimming for each individual LED.

The IS31FL3731 is a nice little chip – and it runs happily over 3.3V power. Inside is enough RAM for 8 separate frames of display memory so you can set up multiple frames of an animation and flip them to be displayed with a single command. Since it uses I2C, it takes up only the SDA/SCL pins on your Feather and can share those pins with other I2C devices and sensors.

Our graphics library makes it easy to draw shapes, text and bitmaps for some strikingly beautiful LED displays. Check out the tutorial for assembly instructions, arduino example code, pinouts, schematics and more!

LED Charlieplexed Matrix – 9×16 LEDs – Warm White

These are 9×16 Charlieplexed LEDs designed to match with the Adafruit 16×9 Charlieplexed PWM LED Matrix Driver – IS31FL3731. You don’t get any resistors or driver chips with this grid, its just a mess of LEDs in a charlieplexed arrangement

This is the Warm White version. Check out our other colors!
