Adafruit CharliePlex LED Matrix Bonnet - 8x16 Yellow LEDs

The Adafruit CharliePlex LED Matrix Bonnet features a 16×8 grid of yellow LEDs driven by the IS31FL3731 charlieplex driver over I2C. Simply plug it onto any Raspberry Pi with a 2×20 header for a bright, programmable 128-LED display — no soldering required.
