I'm fairly new to working with microcontrollers and circuits and I need to power the Arduino Nano 33 BLE sense rev2 with a battery so I can test the on-board Bluetooth without it connected to my computer through the USB port(how I usually power the board.) Ive looked at the board docs and see that It requires 3.3 volts and I cant figure out the best way to do this. should I use 2 aa batteries in a battery holder with leads? a lipo battery? a lower voltage battery with a boost converter?
If anyone could give me any insights into what worked for them or suggestions on the best way to power my board that would be amazing!
