Nano 33 IOT power input?

Official Hardware Nano Family Nano 33 IoT

Hi guys,

i'm pretty new to single board area...
i'd like to build my project with Nano 33 IOT...
the specs page made me confused, cause my english is not so good...

"Arduino Nano 33 IoT only supports 3.3V I/Os and is NOT 5V tolerant so please make sure you are not directly connecting 5V signals to this board or it will be damaged. "

i was thinking that to power my arduino with power bank..
However it says input/output only 3.3v?
Then is it possible to connect with powerbank? or do you have any ideas?

Thanks!

You can supply the USB directly from a power bank.
The on-board regulator will take care of that particular voltage difference.

If you read that statement a little closer "only supports 3.3V I/Os" that is the important part.
Do not supply more than 3.3 to the input output pins.

Bob.
