You can even chain up 62 breakouts to control up to 992 PWM outputs (which we would really like to see since it would be glorious)
it should be simple to adapt it to any other microcontroller
but if you need one
This conductive fabric has different resistance in each direction: 46 ohms per foot across the rows (stretchier direction) and 460 ohms per foot across the columns (less stretchy direction)
Adafruit Mini 0.8" 8x8 LED Matrix w/I2C Backpack - Pure Green DC As of Oct 26What's better than a single LED? Lots of LEDs! A fun way to make a small display is to use an 8x8 matrix or a 4 digit 7 segment display. Matrices like these are 'multiplexed' so to control 64 LEDs you need 16 pins. That's a lot of pins, and there are driver chips like the MAX7219 that can control a matrix for you but there's a lot of wiring to set up and they take up a ton of space. We feel your pain! After all, wouldn't it be awesome if you could
