Mkr fox 1200 powered by battery [resolved]

hello,
can we connect 18650 battery (4.2V) instead of 2x1.5v alcaline ?

thanks

It is, a very generic question, it will depend on what you want to feed with it. For example, if it is to feed a portable FM receiver, YES, if it is to feed a digital system, something critical in its requirements, a specific adapter would have to be implemented.
Give more data for a more precise answer.
Greetings

i found the datasheet : Vmax is 3.6V so i need a regulator between battery and mkr
