Boron / Xenon / Argon Carrier for Outdoor Applications

I think I need to put a Real Time Clock on this board to enable sleep and improve time based functionality. There are two BIG reasons for this:

  1. The 3rd Generation devices have no real time clock so the cannot do time functions (like Time.minute()) until they connect to the network.

  2. You cannot use wake on time for DEEP sleep preventing lowest energy usage.

Thoughts? Comments?

I will post a new design once I have it.

Thanks, Chip
