hi all.
not sure post question please move correct section.
using 7" touch screen on raspberry pi 3. if power screen , pi own power supply fine , pi's red led stays on , rainbow block not on screen.
when power pi screen using 1 power 5v 2 amp supply led flash , off @ stages , rainbow block on screen telling me volts has dropped below 4.65.
here strange thing. if measure volts , amps using usb charge doctor on power supply goes screen show volts @ 5.01 , amps 0.704a . placed charge doctor between screen , pi , volts drop 4.73 , amps show 0 (not sure why shows 0).
pi works, have not seen issues yet if pi showing power low fix it.
question if want power screen , pi same power supply should volts , amps of power supply drive both screen , pi , not have power issues ?
