Vin input voltage level


I recently bought an Arduino nano 33 BLE. The product page does not specify if pin marked as "Vin" can be energized with 5V or 3.3V. What should be that input voltage?


The input range of the Vin pin on the Nano 33 BLE is 4.5-21 V. So you can not power it at 3.3 V from this pin. If you want to power it at 3.3 V then you can do that via the 3.3 V pin.

Thank you !!!

You’re welcome. I’m glad if I was able to be of assistance. Enjoy!
