hey, people knowledgeable in #electronics , I have a dumb question:

I have a 16x16 panel of rgb leds (WS2812B ? not 100% sure, but 5v IN)

I want to pilot it with a RP Pico 2W.

If I have a beefy enough USB charger / battery, is it safe for everyone to use the usb plug of the RP Pico, and get the 5v Vin power for the panel from the Vbus pin of the RP pico? Will it provide safely the multiple amps the panel needs? (how much exactly? can't find) for full white light?

@corpsmoderne If they had bothered to use the proper connector in this day and age (Type C) then you might have been OK with up to 3A or even 5A. But with the micro-B, probably more like 1.5A or so is safely supported.
