How long can a Croduino Damba run on a single battery?

Soldered Support:
Battery life depends mostly on what operations the microcontroller performs. For example, the ATtiny85 draws 0.1µA in power down mode, while the LED on the Damba breakout draws 10mA. For more information see: Soldered: Open-Source Electronics, Boards, Sensors & Modules – Soldered Electronics
The CR1220 battery that fits the holder on Damba has a capacity of 350mAh. If you do not optimize your code for battery efficiency, runtime would be around 14 hours.
Original message (Croatian)
odgovor u najvećoj mjeri leži u tome koje operacije obavlja mikrokontroler. Primjerice, Attiny85 povlaći 0.1uA u power down modu, dok LED dioda na breakout-u Dambe trosi 10mA. Za više pročitajte: Soldered: Open-Source Electronics, Boards, Sensors & Modules – Soldered Electronics
Baterija CR1220, koja odgovara holderu na Dambi, ima kapacitet 350mAh. Ako programski kod ne biste prilagođavali štedni baterije, trajanje bi bilo oko 14 sati.
