Logic Level question regarding Wemo D1 mini

I am controlling a DC motor via a Pololu VNH2SP30 driver. The microcontroller I am using is the Arduino Uno. Power for the Arduino is coming from the USB port, so its 5V and the VNH2SP30 also gets its 5V from there.

All works well, no problems. Now I want to try using a Wemo D1 mini so I can make it an IOT device. Am I correct that this will only work if I put a Logic level converter in between as the Wemo runs on 3.3V logic?

By "in between", do you mean between the D1 Mini and the Uno? If so, what sort of connection are you making between the boards?

By in between I meant the motor driver and the microcontroller, where the D1 would replace the Uno entirely.

If I'm reading the motor driver datasheet correctly, it specifies 3.2 V as a minimum high logic level, which gives no margin on a 3.3 V microcontroller without some sort of logic level converter or driver in between.

Ok thats what I thought, thanks for looking into it.
