Oct 22 '21 at 19:22 comment added bobflux Check this answer and the links inside ; i've tested a few of these and they are definitely not LM2596, also they use super low quality capacitors that will die quickly, output ripple is huge, etc.

Oct 22 '21 at 12:17 comment added bobflux @pasabaporaqui Yes, I said if you need high power (like 1A) then you should be using 24V and point-of-load buck converters. For a bunch of devices that will use a couple tens of mA, like arduino, microcontrollers... or sensors that will use a couple mA or less... 5V down to 3V3 is more economical.
Oct 22 '21 at 9:57 comment added pasaba por aqui 5V common line to power 3.3V devices gives you a margin of around 1.5V. Power 5 devices of 1A is 5A total, with a line AWS20 of 33ohms/1000m means a maximum length of 1.5/(5*0.033) = 9 meters maximum length.
