Arduino Nano 33 BLE External power led indicator

Official Hardware Nano Family Nano 33 BLE

I have a simple question.

My Arduino Nano 33 BLE is build in a case. So, when it is powered on i cannot see it.

I like to have an external led that indicates that the board is powered ON.

Wich voltagepin is the best to use?. I have read that when 5v pin is needed then you have to bridge 2 pads to get the 5v working.

I like to use the 3.3v output for the external led. But, is that possible? Do i have to connect the led directly? Or do i have to add a resistor in line between the 3.3v and the led ??

I do not destroy the board so i need some advice!

Who can help me with this 'simple issue' ??

Tnx
Marc

Yes, its possible. No. Yes, 330 ohm would work real good.

It will automatically close after a while (4 months currently). But marking it with a solution (thanks for that) is sufficient; you can see it as your selected solution was added to the opening post.
