Adafruit 15x7 CharliePlex LED Matrix Display FeatherWings
Adafruit 15x7 CharliePlex LED Matrix Display FeatherWings can be paired with any Feather Boards for a beautiful, bright grid of 105 CharliePlexed LEDs. The FeatherWings come with a built-in CharliePlex driver that is run over I2C. The FeatherWings are available in Red, Blue, Green, Yellow, Warm White, and Cool White. The I2C LED Driver has the ability to PWM each individual LED in the 15x7 grid for beautiful LED lighting effects without a lot of pin twiddling. The LED Driver can be easily programmed to address each LED individually. Each individual LED also offers 8-bit (256 level) dimming.
The Adafruit 15x7 CharliePlex LED Matrix Display FeatherWings are based on the ISSI IS31FL3731 LED Driver. The IS31FL3731 runs over 3.3V power with enough RAM for 8 separate frames of display memory. Multiple frames of an animation can be used and flipped to be displayed with a single command. Since it uses I2C, it takes up only the SDA/SCL pins on the Feather and can share those pins with other I2C devices and sensors.
