Hi - I'm working on a fairly simple PCB that will use USB for power. Why USB? I want to be able to hand this out to people and have them be able to power it easily. Without batteries.
Now - is there any way to draw half an amp off of a USB power supply without having a USB device controller on there? I don't plan on having any sort of smart IC on this board. Is it best to just connect my load to +5V and GND and pray?
