Can run for over six months on 2 AA 1.5V batteries with typical usage. .
The design includes the ability to power the board using two 1.5V AA or AAA batteries or external 5V. Switching from one source to the other is done automatically.
A good 32-bit computational power similar to the Zero board, the usual rich set of I/O interfaces, low power SigFox communication and the ease of use of the Arduino Software (IDE) for code development and programming. All these features make this board the preferred choice for the emerging IoT battery-powered projects in a compact form factor.
The USB port can be used to supply power (5V) to the board.
The Arduino MKRFOX1200 is able to run with or without the batteries connected and has limited power consumption.
You can find in the Getting Started section all the information you need to configure your board, use the Arduino Software (IDE), and start tinker with coding and electronics. Full details and examples on how to use the SigFox interface are available in the SigFox Library reference page.
