We are having a debate on the implication of powering this circuit. The image is only a snipped of the complete hardware- but the debate arises from providing power using a PIN header connected to the +5v bus located somewhere else.
I suggested not to do this and rather connect to the usb +5/gnd pins as the +5v should be used for supply of external circuits and not really to power the entire hardware.
Will the filtering caps have any relevance if we put +5v on the +5V0 Rail instead of VBUS from the USB connector; like originally designed?
Will this circuit actually have any benefit at all?
Would powering the circuit using the TP1/2 be better than directly powering +5V bus?
It is not powered from a PC but a USB charger rated at 5v 1A - The device peaks 500ma~800-ma depending on what its doing. People want to connect 2A or higher to the 5v0 pin because they cannot find a USB charger with that sort of output. I am trying to establish what can happen if the +5 is connected after this circuit instead of how it was desinged.. from the USB port side.
