Anyone know how much current can be pulled on the 3.3v output pin of either the Amico nodemcu v2 board or the lolin v3 board?

I am attaching a string of ws2812b LEDs to this board. So far I have 12 and it does not seem to be problem when being powered by the usb port. I am thinking that a string of 30 or so LEDs will produce enough light but I can’t find any details on how much current can be drawn from the board.
