I'm happy to run a group buy for just the 8736.My last quote from the vendor was just a bit under $27 each, and that does not come with the board connector. I picked these boards for compatibility with Motorola footprint, but also because it doesn't insist on goofy 3.0 volt power and logic

I guess it's time for me to finish up that NTP cape for the BeagleBone. I'm using a Furuno GT-8736 ( http://www.furuno.com/en/ products/gnss-module/GT-8736 ) I built up a prototype about two years ago but... got married very shortly after that and haven't played with it since. Is there any

From: Hal Murray That should work. I haven't found a GPS with PPS for the beaglebone. What level of accuracy do you want? If you only need 100 ms or so, then a normal junk GPS (no PPS) on USB should work. == This works with the BeagleBone:
