Adafruit have a free tutorial to get you started. Or you can DIY your own setup, just follow the LED grid schematic in the IS31F元731 datasheet. Not all addressable LEDs are NeoPixels.CircuitPython library to support MAX7219 LED Matrix/Digit Display Driver. This neat combo lets you drive 144 x 0603 individually addressable surface mount LEDs using just 2 x I2C signals (CLK and DAT).
They work perfectly with the matrices we stock in the Adafruit shop and make adding a bright little display trivial. Connect up to eight 8x8's together on a single I2C bus.
