Since the Zero W doesn't have a polyfuse, am I right in assuming that the 5V pin can safely supply whatever current the power supply puts out minus the draw from the Zero W board itself (and any attached items)?
I'd like to power 4x devices with a max draw of 500mA each. My power supply provides 2400mA. According to this, the typical bare board consumption is 150mA. I don't have any USB devices attached which means I end up with 2400-500*4-150 = 250mA overhead if all 4 devices are on full load.
Is this correct? Is there any reason not to do this?
