Need some help here to power on the board. I am a newbie at this but from what we have found researching this online we are supposed to connect the red wire on our AA battery holder into the vin or the 5V and the black wire into the ground.
I done this but it still does not power on the board. I don't know what's up with it because as far as I know this is how we supposed to power the board. I used 3 1.5V AA batteries with a six battery holder.
Can you guys please help us find a way to power this on. Have some pictures so you guys can better understand the issue I am dealing with.
The Vin pin will accept from 4.5V to 21V and the onboard voltage regulator will regulate the voltages down to that required by the board (3.3V) but it cannot do this if the input voltage is too low, which yours might be
On a classic Nano you can also choose to feed 5V to the 5V pin directly and bypass the onboard regulator. However, the Nano 33 IOT is, as its name suggests, a 3.3V device and whilst it does have a 5V pin so that it can supply 5V to sensors if required you must enable this output explicitly by shorting out the relevant pads on the bottom of the board.
Even if you short the 5V enable pads you cannot use the 5V pin to supply power to the board as it is purely an output
It sounds like your best option would be to power the board either from a USB connection to a PC or battery bank
Are you sure you get a voltage out of your battery holder? I would expect all slots to be in series and therefore only work when all batteries slots are filled.
I also recommend you have a look into a 18650 to USB battery board or a power bank. WiFi requires a lot of power and will eat your battery for breakfast not leaving much for dinner. RF also creates fast current surges that some cheaper batteries my not be able to source or only for a short amount of time before you have used them up. Rechargeable batteries are better suited for these type of applications.
