Which route did you take-- PPS pin to RS232 (CMOS level) or via the
buffers/inverters?
All I am pointing out to people who might regard the sure board as a
really cheap path, but do not have the soldering skills is to beware. If
anyone feels that they can solder to surface mount devices, and have the
tools (really fine, temp controlled soldering iron), go for it. It is a
cheap way of getting accurate time. And the usb power in and NMEA output
are really nice.
I used the inverter and RS-232 level convertor route, as shown on my Web
site:

The two wires required are clearly shown. Certainly if you (or a friend,
or a workplace or local TV repair shop) don't have skills or soldering
equipment, it's not a project for you, but you don't need special
surface-mount soldering equipment. A little care and fine soldering tip
are required. Any one who might be interested can look at:

and make their own judgement.
