I'm wondering about what 5V power supply to get for powering the cube...
What would be the maximum current consumption of the two solutions when all the LEDs are turned on at full brightness (assuming we give each LED 20 mA of current)?
With the MAX7219 I saw something in the datasheet that it consumes 330 mA, but I wonder if that includes the current consumption of the 64 LEDs it drives or it consumes 330 mA by itself...
Any useful tips regarding the power supply?
Thanks,
Andras
