PropSTICK USB power supply question

can the PropSTICK USB draw it's power from the usb connection by any chance? just thought it'd be kinda neat if you could hook it up to the computer all on its own for programing without having to supply an external power source.

    Theoretically it can, but it's not designed for it. You could add a tiny little jumper from the 5V terminal of the mini-USB connection to the regulator's input (Vin). The problem is that there are very specific restrictions on how much power can be drawn from the USB port at any given time and the PropStick has to be designed to conform to that. There have been several threads here discussing it.
