adafruit ultimate gps hat - mrjake - 02-16-2017
https://learn.adafruit.com/adafruit-ultimate-gps-hat-for-raspberry-pi
since the pine 64 uses the pi2 pinout, would this work with my pine64 2gb?
Im looking to make a cheap but reliable NTP server to provide accurate ime to other ntp servers on my network.
Thanks

The UART should be no problem, but PPS support you have to do some work, check which pin is used here first. I think someone added PPS support to a Pine a while ago (use search). Basically you have to add the devicetree entry defining the PPS pin and add the PPS driver to your linux kernel.

... check !! in addition you may have to add a pull-up or pull-down resistor to the hat. be careful.
