Outputting 5V on MKRNB1500

[johndoes]

So the microcontroller on mkr nb1500 runs at 3.3V and we can't apply more than that on the analog and digital pins.

But, can the digital and analog pins output 5V? or is that a no-no

the Circuit Operating Voltage is 3.3V and so that's what you'll get from the Digital I/O Pins.

if you want 5V you'll need a voltage converter at the back of the pins.

If it's just a signal, then you can consider an I2C level shifter that are readily available with 2, 4 or 8 pairs of matching pins.

You supply 3.3V on one side, 5V on the other side, connect the GNDs and then the signal coming in on one side is transformed into the same signal (HIGH or LOW) on the other side, with the other voltage (works in both directions)

@J-M-L

if you want 5V you'll need a voltage converter

Or just use a transistor to switch the higher voltage...

yes a transistor can be used as a voltage converter indeed (and/or to control more power)
