Is there a definitive answer to this? And is there a difference between let's say Pi 3 and Pi Zero? I can't seem to find any "confidence inspiring" information on the topic...
I know for a fact (probably) that one can draw from the 5V pins as much current as the power supply can supply.
The 3V3 pins, on the other hand? 50mA? 800mA? Each or all? Everyone claims different values.
The GPIO pins are said to handle a max of 16mA each, but no more than 50mA in total. Is this still relevant to the new Pi's that have the 40 pin layout? And they can't handle more than 3.3V, right? Is there a difference in these values depending on whether it's input or output?
I am rather confused... Any help would be greatly appreciated!
Happy almost New Year!
P.S. I know this is on the subreddit, as well. I am in quite a hurry to start prototyping my design, but without the fundamentals, rather difficult it is.
