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.

What does that mean? could anyone explain it to me, please
 MKRZero runs at 3.3V or V5? if we say The maximum voltage that the I/O pins can tolerate is 3.3V, why it has VIN 5V?
should connect one sensor 3.3 on MKRZero or the total of sensors on the device should not be more than 3.3V?

In your opinion Which Solar Power Manager is suitable to work with Arduino MKR Zero?
1. CN3791 MPPT Solar Panel Regulator Controller Module.
2.Waveshare Solar Power Management Module for 6V~24V Solar Panel.
3.Solar Power Manager (for 9V/12V/18V solar panel)
4.Solar Power Manager Micro (2V 160mA Solar Panel Included)
