interesting, what kind of applications are you thinking about that involves wireless combined with a RTC?
What can you think of that needs wireless and couldn't have a RTC smiley-grin
This board is a 3.3V board. The maximum specified frequency in the datasheet for 3.3V is around 13MHzso I chose 12MHz.(* jcl *)
OK, that makes sense. Although some vendors 'stretch' those specs and run boards at 3.3vdc and 16mhz and report no problems. I however certainly do not endorse doing that, just seen it done by Seeeduino and a few other clone vendors.Lefty
