Here is the specs and limitatons:
* It has to be a desk clock and weather station combo, using a battey-backed RTC and a combined temperature and humidity sensor like SHT30-DIS.
* The form factor must be no larger than a small stack of credit cards - no bigger than a credit card, no thicker than 1 inch.
* It must be able to run on internal battery with full functionality for at least 2 hours.
So, wha would be your most overkill implementation?
