Hi all, Should anyone face the same problem, I found the root cause: brownout threshold. I burned a new bootloader (Optiboot 8.0) without such trigger and the node has been working with used batteries (~2.7V) since May. Hope this helps.

The product listing for the step-up that the OP is using says: Sucks the juice out of your batteries. Sounds like it delivers on what it promises....

Can you tell something about the range of this node? And do you see a chance to post the schematic?
