Just got my BrickPi here, (normal, no power upgrade, which I never ordered because I didn’t even understand what it meant)
Connected this to a 9v 500amp adaptor, the red light on the pi comes up, and the green blinks, but I get nothing on the other lights
Connecting the pi directly via the usb power made the image you supplied work (I wonder why you cut out the screen output, but does not matter that much)
I have no 6 aa to 9v adaptor yet, so I didn’t do that
I have read on the forums here about people powering the pi directly, about people using 6v 2amp PSU, and many other answers.
So what I would like to know, is what will officially work, what psu should I buy (for immobile setups), and what is the voltage variance and amps needed, as I don’t want to fry this just yet
