I was doing some more messing around with the snooze library and cpu speeds when I noticed that if I had an SD card inserted in my Teensy 3.6 while I was hibernating, it uses 500 uA vs 60 uA.
I also noticed that while running at 24 MHz a card inserted also raised my operating current by about 20 mA while idle.
I will spend some time investigating this weekend, but I thought I would ask here to see if someone could beat me to it:
Is there a way for me to shut down the sd card and then remove power from to the card before I go to sleep in order to save power?
