    Description-

    You wont be able to look away from the mesmerizing patterns created by these Adafruit 15x7 CharliePlex LED Matrix Display FeatherWings.  These 15x7 LED displays can be paired with with any of our Feather boards for a beautiful, bright grid of 105 charlieplexed LEDs. They even come with a built-in charlieplex driver that is run over I2C.

    We carry these FeatherWings in five vivid colors!

    What is particularly nice about this Wing is the I2C LED driver chip has the ability to PWM each individual LED in a 15x7 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.
