i'm working on building portable pi using xbox chatpad interfaced through gpio , battery pack: https://www.piborg.org/battborg. unfortunately, because both occupy first 26 gpio pins, can't use 3.5 inch adafruit touchscreen. found nice 5 inch screen looks work: http://www.adafruit.com/products/2110. have 1 problem though, want power via 9v battery, 1 use in smoke detector. however, these produce around 250-500 mah of power. have specifications or estimates power draw of display, , if 9v battery work? appreciated.
