I've been trying to find the answer to the same question. Currently I have a >2A supply connected to the official RPi display, then powering an RPi2 via the GPIO jumpers. HOWEVER, this is currently just an RPi and display... I plan to install a HiFiBerry DAC+ and FLIRC, and maybe wifi dongle. At that point, the GPIO jumpers won't work (without soldering?). I am also concerned when I add a FLIRC to the RPi. I've ordered a micro-USB "Y" cable - idea would be micro-USB wall-wart (>2A) to "Y" cable, with one connector to micro-USB on display, second to micro-USB on RPI. I haven't tried yet, but ideally the RPi2 is OK powering the FLIRC (and wi-fi dongle if I add) via its USB ports. For this setup I'd prefer NOT to have to add a powered USB hub. I have "funded" a kickstarter RPi+Screen case, and I'd like the final configuration to look as clean as possible. My original RPi setup is a little different - I have an RPi B+ with a HiFiBerry AMP+ and an AdaFruit 5" 800x480 HDMI display, FLIRC and WIFI dongle. In this case, the AMP+ (12V supply, I think) provides power to the RPi via GPIO. The AMP+ however, isn't designed to power more than just the RPi on the 5V. In that configuration, I have a powered USB hub which provides power to the display (power only via USB) and to the FLIRC and WIFI Dongle (power and data). I'd rather NOT have two power supplies and a USB hub, but it works OK in that configuration. ------------------------------------------------------------------------ tcutting's Profile: http://forums.slimdevices.com/member.php?userid=17402 View this thread: http://forums.slimdevices.com/showthread.php?t=103330 _______________________________________________ unix mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/unix
