    Maximum Number of WS2812 Addressable LEDs with AVR-based Microcontrolllers

    If you are using an AVR-based microcontroller for large LED installations, there is a limitation with the number of WS2812s LEDs used. This is dependent on the microcontroller's memory and the size of the program. For an ATmega328P-based microcontroller (i.e. RedBoard Programmed with Arduino, Arduino Uno, Arduino Pro Mini, etc.), it can be up to ~300-400 LEDs. Looking online, it looks like someone has documented the maximum number of pixels for a few AVRs here:
