Raspberry Pi 2 B - Illuminated Power Switch

j666gak

Hello,

 

I have been searching across the forum for articles relation to adding a power button, however all of the posts either refer to using GPIO pins 5 & 6 which I am already using for the offical 7" touchscreen.

 

  • Can either momentary or latching switch be used?
  • Which GPIO could be used instead on pins 5/6? or does it have to be 5v and ground
  • On the switch would you normally NO (Normally Open) or NC (Normally Closed) terminal?

 

Thanks for your help in advance.

    Hello Guy,

    O think that the best solution to manafe a power button is just using pins 5 and 6

    There more power options instead to power both the PI and the touch together. Tje most affordable is to power the lcd micro USB and connect the PI from the second ISB B on the display controller board to the micro USB. Then you have both the devices connected with a single power line. Then with your power unit connected to the pin 5 and 6 the entire system will work as expected.
