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

[folkert]

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
