## Description

The Adafruit 15×7 CharliePlex LED Matrix FeatherWing in Yellow adds a bright, compact 105-LED grid to any Feather board. The onboard IS31FL3731 driver handles all the charlieplexing over I2C, with 8-bit (256-level) PWM dimming on every individual LED — no complex wiring needed. The driver chip includes RAM for 8 separate frames of display memory, allowing you to set up animations and flip between them with a single command. Since it communicates over I2C, only the SDA and SCL pins are used, leaving the rest of your Feather's GPIO free for other peripherals.
