[time-nuts] Suggestion for a timing GPS receiver (Trimble / Ublox / other?)

[Mark Sims]

I put my layout for a GPS RS-232 level converter board up on OSHPARK's shared projects.   It has places for mounting the Trimble Res-T, the Adafruit Ultimate GPS, and the CN06 (Ublox 6M).  The RS-232 circuit has a selectable polarity 1PPS ouput.  You can use a3.3V or 5V regulator or there is a jumper for providing the receiver with the raw input power.
