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.\n\nThe 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.\n\nKey Features\n\n\n15×7 LED Matrix – 105 yellow charlieplexed LEDs\n\nIS31FL3731 Driver – I2C control with individual 8-bit PWM dimming\n\n8 Animation Frames – Onboard RAM for storing and switching display frames\n\nWorks with Any Feather – Shared I2C bus leaves other pins free\n\n3.3V Operation – Direct compatibility with Feather boards\n\n\nAlso Available\n\nBlue\nGreen\nRed\nWarm White\nWhite\n\n\nIdeal For\n\nScrolling text and status displays on Feather projects\nLED animations and lighting effects\nData visualisation and bar graphs\nWearable electronics with visual feedback\n\n\nPackage Contents\n\n1× Adafruit 15×7 CharliePlex LED Matrix FeatherWing – Yellow\n\n\n\nNote: Feather board not included.
