Powering a device from pixhawk

Hi All - sorry if this is a simple question but I need to power a small LORA radio board from my pixhawk. I need 3.3v and I'd like to be able to make this 'plug and play' from the pixhawk (3DR version) if at all possible. Any ideas?

  • ah great. I have a few spare plugs for that. Thank you.

  • Spektrum/DSM port vas 3v3.

  • ok but where do I draw the 3.3v from? The AUX ports?

  • no problem, 30mA is ok.

  • the board I want to power draws 30mA

  • It's not a simple question, as you did not post the operating current of the device at 3.3v.
