Amazing Device (One ADC Question)

[Phil]

I have the GPY and with the solid sample code was able to have a very reliable LTE-CATM1 communications, reading 1 wire sensors and utilizing deepsleep for long battery life. I am amazed how well it works.

I am also interfacing with the Pytrack, is the ADC2 working now so I can use pin 9 on the pytrack header? Should I go with an external ADC, if so, can I power it with the 3V3 Sensor out that is controlled via deepsleep?

Also when I go_to_sleep() should I set true to for GPS what are the pro's and Con's of doing that.

Thanks!
