i've been using the Nexus Machines LED matrices with Arduino, that have the MAX7219 chip built into it, but now i'm building my own, and i cant find any details on whats the maximum specs of LEDs you can use with the chip. i need them to be as bright as possible while still working on 5volts from the arduino board.
i've checked through the data sheets a million times and cant seem to find anything. am i just blind or what? :-?
cheers,
bod.
