You wont be able to look away from the mesmerizing patterns created by
this Adafruit 15x7 CharliePlex LED Matrix Display FeatherWing. This
15x7 LED display can be paired with 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.

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.
