Thanks for contacting us.
I would like to let you know that all the information regarding the Intel Joule platform is available on this site: Discover the Intel® Joule™ Compute Module (Expansion board Hardware Guide, Design Guide, Compute module Datasheet, etc.) That information is updated periodically, however, at this time we don’t have a specific date for that.
I looked for the details you are asking for regarding the Real Time Clock (RTC) and as you have mentioned it is limited, so I would like to let you know that I’ll submit your request to the proper team, so they can be aware of and take it into consideration for a future update.
Hope this help.
