Adafruit 15x7 CharliePlex LED Matrix FeatherWing - Cool White

Experience mesmerizing light patterns with the Adafruit 15x7 CharliePlex LED Matrix Display FeatherWing in stunning Cool White. This 15x7 LED matrix features 105 charlieplexed LEDs controlled via a built-in I2C Charlieplex driver.

The IS31FL3731 driver chip enables 8-bit (256 level) PWM dimming for each LED independently, allowing you to create beautiful lighting effects easily from your Feather board using only the I2C pins (SDA/SCL).

Key features include 8 frames of display memory for animations, compatibility with all Feather boards, and a compact design measuring 51.0mm x 23.0mm x 3.0mm (2.0" x 0.9" x 0.1") weighing just 3.8 grams.
