MKR NB 1500 I/O pins max voltage


Are the I/O pins capable of handling 5V or 3.3V on the MKR NB 1500?

On the product page for other MKR boards such as the 1000 or Zero, there is a warning:

Warning: Unlike most Arduino & Genuino boards, the MKRZero runs at 3.3V. The maximum voltage that the I/O pins can tolerate is 3.3V. Applying voltages higher than 3.3V to any I/O pin could damage the board.

But on the product page for the 1500, there is no warning.

I’ve purchased a board, I’ve got it connecting and sending data to my webserver, which is awesome!

But before I continue and add sensors without voltage dividers, I’d like to know if 5V on the I/O pins is safe.

if you look at the Schematic it seems the SAMD21 Cortex®-M0+ and SARA-R4 pins are directly connected to the headers so I would think it’s like the rest of the MKR family - don’t go over 3.3V
