Adafruit LED Charlieplexed Matrix - 9x16 LEDs

These super-cute little 9x16 charlieplexed LED matrices have 144 LEDs which can be independently driven and PWMed to your hearts content.

Combine with the handy little I2C backpack for the ability to PWM each individual LED in a 16x9 grid so you can have beautiful LED lighting effects, without a lot of pin twiddling. Simply tell the chip which LED on the grid you want lit, and what brightness and it's all taken care of for you.
