Battery based atmega328p sensor with SMD nrf24l01+

@GertSanders ATSHA204A is working fine on your node. I finally have built a full node with ATSHA204A and SPI EEPROM.

I am really interested in checking it out! Also the relevant sketch to understand how the battery operations are really supported esp. with interrupt handler et al.

@vikasjee
Alex used the hardware described at the start of this thread.
You will find all design documents on Openhardware.io
