I am working on Simple Audio Frequency Meter using Arduino MKRZERO board.
I am confused about the connection of IOREF pin shown on the above page.
This pin is missing on the MKRZERO board. Which alternate pin can I use ?

Thanks in advance !

Hi @vjirgale,

You can use the VCC pin, IOREF is 3.3V on the Zero, VCC pin is 3.3V on the MKRZero.
