Hey
I'm just starting with Arduino so please forgive me my ignorance.
I want to build a portable device using either Arduino 33 Iot or BLE, haven't decided which one yet.
Ofcourse being portable it needs batteries, but I just can't find any good answers to this question.
What's the best battery solution for this matter? I want to use Lithium-Ion.
I've read that Arduino nano can use battery packs from 6-20V, but I don't know if this is also the case for the 33's?
Thanks in advance
Brent
