It's not super straight forward from the docs on github but

Longer explanation: deej uses potentiometers as voltage dividers between a 5V pin and a GND pin. Since each analog pin (the pin connected to the pot's wiper) has its own "circuit", each pot is treated as its own voltage divider and is always the only resistor across that circuit.

So basically as long as the max voltage that the pins operate on is 3.3v, then that is the correct voltage to use.

Here's a wokwi example I put together with an esp.
Keep in mind oyu need to map the values because the ESP ADC does 0-4096
