Adafruit 16x9 Charlieplexed PWM LED Matrix Driver - IS31FL3731

Adafruit 16x9 Charlieplexed PWM LED Matrix Driver - IS31FL3731The IS31FL3731 will let you get back to that classic LED matrix look, with a nice upgrade! This I2C LED driver chip has 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. The IS31FL3731 is a nice little chip it can use 2. 7 5. 5V power and logic so its

who already know how to use NeoPixels and are comfortable with the high current requirements and protecting the matrix from damage

We have a ton of other NeoPixel rings in the store to check out
