I have be trying to research how I would go about powering 3 Raspberry Pi devices using only 1 outlet. The raspberry pi require 5v and a max of 2a. I think I know just enough about electronics in general to apply any answers I find here. I am capable of diy what I need to.
Could I purchase a simple 9v ~1a wall wart power supply and split the dc 9v dc power over 3 buck converters that will step down to 5v? Place a diode in before the buck converter for protection?
Any and all advise os greatly appreciated. Thanks.
