☞
The EVK-NINA-B1 has an I/O voltage range of 1.7-3.6 V. It can therefore be used only with
shields that support an I/O voltage within this range.
The EVK-NINA-B1 has a pinout that is compatible with some Arduino or Arduino inspired shields. This
section describes the features of the EVK pins that a shield has to comply with:
 IOREF: The I/O voltage level of the NINA-B1 module. Is 3.3 V by default, but the EVK can be modified
to allow for other voltages (1.7-3.6 V).

RESET: Is connected to the RESET button (SW0).
