Power the Larson Scanner from a Raspberry Pi

Hello from the UK!

I've just built my Larson Scanner - which is a great kit - thanks. I'm going to be using it near a Raspberry Pi. Is it possible to use the Pi's 3.3v output via GPIO to run the scanner?

Thanks in advance,



  • Yes, that should work fine, without any changes.  If you're running anything else off of the 3.3V line, then you should double check to make sure that you're not pulling too much current. If I understand correctly, it's only rated for 50 mA output.
  • Great, thanks Windell.
