[App_rpt-users] Beagle Board-xM + LOX OS and power consumption

[Tim Sawyer]

Can't help you there. Don't know but I bet the RTCM is pretty low current draw.

This device is so new, it is hard to understand just what to expect from it.  WB6NIL rewrote the firmware for it very quickly, so it is definitely a moving target, but seems to be improving with each iteration.
