Is there a Hardware Compatibility List for PPS devices or GPS units with PPS?
I’m interested in a low cost GPS unit, with PPS and a USB interface.
Raspberry Pis and other single board computers have a hardware GPIO interface for a TTL PPS input, and that approach might need it’s own hardware compatibility list.
But what about standard PCs? Are there standard GPS units that work with USB-3 and provide PPS?
This is a pretty common interest. Where’s the list?
