Adding resistor to R44 to power Raspberry Pi from Aux input

richardbeattie
richardbeattie over 7 years ago

Hi all,

 

I am trying the get the audio output to an external set of speakers soldered to the speaker headers. As according to the manual I have tried to power to card through its Aux input, however this didn't work. After some googling I cam across

  • speaker connections
  • External 5v supply  instructions missing in user manual?

 

Both of these tell of how by default the aux power cannot power the raspberry pi along with the card, however by soldering a resistor to R44 it can be done.

 

My question is does anyone have any experience with doing this? Wouldn't the resistor need to connect two places, so where else do I solder it to?

 

Thanks,

Richard
