Nano 33 BLE 3.3v pin not working

Official Hardware Nano Family Nano 33 BLE

Hi,

I'm new(ish) to Arduino and I have a small question with my Nano 33 BLE:

I'm trying to power a GPS module from the 3.3v pin on the nano, but there's no power on the pin (when I test the voltage between GND and 3.3V it's 0v). I do have it plugged into my laptop with a USB cable, so I was wondering if the nano doesn't supply power to the pin on purpose when it's plugged in, or if it's a USB 3.x problem? Or possibly something stupid I did with the hardware?

Thanks

good day Amy-m,

I am also a fairly new user of Arduino, particularly the Nano 33 BLE. I do use the 3V3 pin to drive chips when my Nano 33 BLE is connect through various USB so, from what I understand, the only reason why you would not get 3V3 is if the solder jumper is cut in the back (Pinout-NANOble_latest.pdf (arduino.cc)) but you would not have any power on your board and would not be able to up load any code. Anyway, if this is the case, you can put a soldering drop to fill in the jumper.

Best of luck.
