Compatibility
I've tested this shield to create an NTP server with both Raspberry Pi 1 Model B and 2 Model B, both of them work like a charm, and should work with any board that uses the original Pi's 26-pin mapping. The other connected pins are not yet tested.
Should work with all normal-size NavSpark variants, NavSpark (GPS), NavSpark-GL (GPS/GLONASS), NavSpark-BD (GPS/Beidou).
