user77950: I bought an Arduino Nano ble 33 but when I try to power my MQ-4 and MQ-8 sensors, these don't turn on at all, they do turn on if I switch to the 3.3V tho.
Is there anything special that I need to do to be able to use the 5V pin, or my board is faulty?

P.S: When I say 5V I mean the pin next to the green rectangle.

user68012: i think you solder the two pads but i'll tell you something: use the 3.3v pin
