WOW, thanks for all the info!!!I will use those cool DC-DC power converters on

I recommend against using an Odroid. What I have heard from friends
is that you do not get any support from the manufacturer in any
way. Which means you have to build your own software st

One might look at the available frequencies and see if there is a
telemetry band available which allows wider bandwidth. For the
application, I don't see that very much transmitted power is needed.

If anybody ever needs help with ntp, feel free to poke me off list.
There are 2 ways to get data into ntp.
You can implement the kernel P

"Problematic" if you are after microsecond-level accuracy, perhaps, but so
would the BeagleBone be. If your needs are more in the 100 microsecond
range, either would be fine with a reasonably wide PPS pulse.
Not really. If you know how to write C, you can use the

Is the new RPi2 any different in that regard?
The RPi 2 has the same basic configuration (Ethernet over USB), but has a
4-core CPU and 1 GB memory, making it very usable as a stand-alone PC. NTP
