Description
Experience mesmerizing light patterns with the Adafruit 15×7 CharliePlex LED Matrix Display FeatherWing in stunning Cool White. This 15×7 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.
