The regulator can supply up to 500mA, so I think it's safe to power the cam and servo from USB power bank (connect the servo to the 3.3v output on the left header). In my case, the servo requires an operating voltage range from 4.8V ~ 6.0V so this will not work for me. http://hitecrcd.com/products/...
