Hey guys,
I'm trying to bring down my 5v voltage to 3.3v. I'm looking at all the different ways of doing it and can't decide what's best.
Voltage regulator seems to be the easiest/safest way for me to do so but it's a bit pricy.
Voltage divider is probably the cheapest, but I was reading that different load draws can make it not work the way its supposed to.
Why can't I just use one resistor like the way it's done for LEDs?
I'm trying to power the USB multiplexer found here:
