It just starts spitting out NMEA data and they work good I use them for time stamping timing critical events on remote nets. If you contact tech support with Maestro you email with "Larry" and this is not much better than the manual but once he understands what you want and stops telling you really basic things off his troubleshooting sheet you get what you need from someone behind the curtain. Given the $20 cost for a fully functional GOS with PPS it is a great deal, even with the poor docs.They are surface mount parts but hand solder very easily.
Regarding the shutdown shutdown stuff I just wait the second then shutdown power.
Thank you so much for responding to my question! So when you say that you just shutdown power after a second, is this after you do the 200ms high/low pulse on the ON_OFF pin or do you just wait for the wakeup pin to go low and then count 1 second after that?
