I would like to add 60 WS2812B LEDS to a new build and I am wondering how to do that. The LED strip runs at 5 V and one LED can draw up to 60 mA (but it’s more like 20 mA on avarage). My initial thought: Get a step down converter that can handle the max current drawn which is 60 mA * 60 = 3.6 A at 5 V. So the first question is: Which one? And is it safe to solder it directly to the 10s4p battery pack? I want to use the firefly remote and I was thinking of modifying the code to put a LED on/off option to the settings menu which will set a GPIO pin (e.g. No 5) on the arduino of the firefly receiver either to HIGH or LOW which than turns on a mosfet, which powers on the LED Strip. Another Arduino is needed to control the LED strip. I draw this picture:
What do you think about this idea? Is it ok to do or will I burn my vesc?
