The GNSSpower and Teensy/IMUpower should both just be K7805M-1000R3, Looks like I used the C5369649 which shows they have stock. The other 2 components I can’t help you with.
Hey there, I am doing the same thing, and when I look up the K7805M-1000R3 it gives multiple options of it with a different package. How do I know which one to select? Thanks!
