[time-nuts] looking for low-power system for gps ntp timekeeping

[David J Taylor]

Hi,

I own a couple of GPS modules (garmin 18(x) lvc) which I would like to
use as a time-source.
Now my server already has such a module connected (via gpsd and a pci
rs232 interface) and my raspberry pies too (adafruit modules) so I'm
looking for a low-power computer with a complete RS232 connector (DB9)
with all signals attached so that I can feed it a PPS. Also real
RS232 so that I don't have to mess with resistors and such.

I'm considering either this one:

or this one:

What do you guys think: would they be any good for timekeeping? Known
issues?

Regards,
Folkert van Heusden

Folkert,

As you already know, your Raspberry Pi with the Adafruit module alone would 
make an excellent NTP server.  About 4 watts power consumption, and lower 
cost than those you list.

What else do you need?

Cheers,
David
