Adafruit IS31FL373 Charlieplexed PWM LED Matrix Driver

Adafruit IS31FL373 Charlieplexed PWM LED Matrix Driver provides a classic LED look with the ability to PWM each individual LED in a 16x9 grid. This feature allows for beautiful LED lighting effects, without a lot of pin twiddling. Using the chip is as easy as programming which LED on the grid you want lit, and the brightness. The flexible IS31FL3731 uses 2.7-5.5V power and logic for use with any microcontroller. The address can be set so up to 4 matrices can share an I²C bus. Inside is enough RAM for 8 separate frames of display memory to set up multiple frames of an animation and flip them to be displayed with a single command.
