My issue with the commonly available NEO-6 boards is that most do not break out all of the features of the module. The cheapest ones bring out the serial pins, but do not utilize the USB functionality. Also, few (if any) provide a buffered PPS signal through an SMA connector. These two features in particular are why I decided to design my own.
|My u-blox NEO-6M breakout board.|
The board has USB for monitoring and configuration via u-center. It also has a buffered PPS output, a backup battery holder, and it works with active antennas. GPS reception on this board is just as good as with any other breakout or Eval kit I've tried.
I'm very happy with how this board turned out. I will be re-using much of this layout in my development of a retrofit GPS board for the Lucent KS-24361 REF-0.
Thanks for reading!
