      I don't think you'd get more than a few mA that way, and it needs around 50 mA.  I'm working on a battery-powered design that would be more suitable.

      Hi Scott,

      An amazingly small unit. Would there be enough power on the mic jack of a Kenwood/Wouxun handheld to run it?

      I was thinking of a board without the USB plug and TRRS socket in an enclosure with Kenwood type plug and USB micro socket that plugs straight into a handheld. Given the price of Icom/Kenwood/Yaesu APRS handhelds I thought it might be worth a try.
