Dumken Member Jul 13, 2015 #1 Hi guys.. Pls can someone help me with the calculation on how to determine the Power consumption of an 8x64 multiplexed led matrix.

D dougy83 Well-Known Member Most Helpful Member Jul 14, 2015 #3 The average power consumption is simply the average LED current (when on) multiplied by the average number of LEDs that are on multiplied by the supply voltage, plus the power the driver/controller uses.
