Hey Arduino Team,

Just wanted to know if the UNO Q is compatible with the CNC Shield, i.e. the below image:

What voltage does the Uno Q use for its digital and analogue pins ?

What voltage does the CNC shield use for its pins ?

CNC will take 12 volts, but the pins from Arduino to shield just for logic is 5v

The voltage of the UNO Q i/o is 3.3v

I have driven these modules with a teensy which are 3.3v also, and it worked.

All the shield's pin uses digital I/O so it should be ok.

Yes, it works I tested it with UNO Q now, Thanx
