I was wondering if it would be possible to directly supply the Arduino Nano 33 IOT 3.3V on the 3.3V pin? Indeed, for my project I need to power the Arduino with 2 AA batteries, and I feel that it is kind of a waste to boost the 2 cells voltage to 5V (or similar) to to have it regulated down to 3.3V. Especially as I would like to save as much battery as I can for the project to last longer.
From what I saw on the schematic (see the attached file), the MPM3610 doesn't have any kind of protection (diode or similar). Would it be an issue?
Also I don't plan on uploading code while the Arduino is powered by the 2 cells ( I think it would be an issue in that case).
