Raspberry Pi Portable Display.

ksharp117

Hello all.

 

I was wondering where/how Ben connected the display to the Raspberry Pi. I've been trying to figure it out by watching the video but can't quiet figure it out.

 

Also, would I be able to connect a display to the B+ the same way.

 

Thanks all.

  • He used a cheap backup camera display.  He used the composite output (yellow) from the Pi and hooked it to the yellow on the display.  He also powered the display if I remember from an external power source because for some reason we could never get the display to work off of 5V when bypassing the switching circuit.  He might have used the output from the switcher to power the Pi, don't quite remember, the only issue is you might overload that IC if you are running wireless stuff, otherwise the Pi doesn't draw that much.

    I was also having problems myself. Am I right to assume he removed the jack/plug from the Pi, and just wired the screen's video data wires direct to the Pi's video output pin where the jack/plug had been? He holds up the board for just a second, to show its new lower profile, and it looks like almost all but the HDMI port has been removed.

     

    [EDIT] Also, with the new B+ board, I imagine the pins/holes will still exist to solder to, eventhough the new composite out is a single interface/plug?
