I'm currently working on a project where I want to control an 8x8 WS2812B LEDs matrix. My goal is to reduce the current consumption as I want to power it using USB port of my pc. The datasheet of WS2812B says that it consumes about 60mA for each led for full intensity. So 64 x 60mA = 3.84 A which is > USB port power
My idea is : To group my leds into gorups of 8 and multiplexing between the groups (turn on one groups while all the other groups are off) fast enough so I can create a POV. As I assume that the consumption will be only about 60mA x 8 = 480mA
Do you think this is possible? Otherwise do you suggest any other solution to reduce power
Appreciate your help
