This 15x7 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.\u003c\/p\u003e\u003cp\u003eWe carry these FeatherWings in five vivid colors - \u003cstrong\u003ethis is the Red matrix.\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eWhat 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.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003cp\u003eOur graphics library makes it easy to draw shapes, text and bitmaps for some strikingly beautiful LED displays.
