What's the maximum draw of the LCD + interface board ?
by the time you have pi2 @1ghz, keyboard, mouse, etc all plugged it I'm thinking to allow any kind of wiggle room probably a 4A power supply would be likely needed (as estimate only) I'm certainly seeing warnings with a 2A supply
While I could use a powered usb hub to take the pressure off I'd rather keep it all more portable and just have the one supply
Any ideas or thoughts on the best way to amply(sorry!) power everything
