This board can be used with the UTC-clock shown on previous post or with other GPS-applications like frequency standards and APRS-trackers. The board is using Fastrax GPS-modules. Other components are just for 3,3V regulation and buffering the signals in and out. There is also a place for a memory capacitor. For a long-time backup, a battery should be used. A baudrate can be selected with jumpers on the board.
Here is the board layout from Eagle:
