Hi there, yesterday I finished the electronics on my Awtrix, and after flashing the D1 through my PC, which was a breeze. the whole thing of course sprang to life, as all was conected, minus the 4A Poswersupply.
The whole thing ran pretty fine with just the USB Power supplied to the D1, which got me thinking, why is the Powersupply specced this high, since your standard USB Power can supply enough juice?
Now i am by no means a electronic wizard, i just well can bolt up shit with instructions and stuff works, but i have no experience with ratings and so on, so maybe someone here can elaborate as to why the recommenced powersuppyl should be 4A and above? And will it be fine to just run the whole shebang through your standard usb charger instead of a beefy 4A Supply? what are the downsides? Im really curious! 😄
