h1. RTC-Test
Companion board for eval-stm32f072xx.
This board should already implement much key features of helios.
* PMOSFET on RTC-Alarm-output enables max1450-blah so MCU is powered by battery.
* Enable-circuit from driver board (Switch 36V).
* WKUP-Button
* Hold-PIN (Power MCU by battery but without RTC)
* Force-Button (Start MCU with battery)
* LED VDD_BAT on enable-pin of max-blah
