Sabertooth with rpi questions

I’m configuring the sabertooth dip switches and I can see a 4X mode which says “If switch 6 is in the DOWN position, 4x sensitivity mode is enabled. In this mode, the input signal range is from 1.875V to 3.125V, with a zero point of 2.5v. This is useful for building analog feedback loops”

So is this going to make it work with the RPI 3 3.3V gpio?

The sabertooth is expecting 5V TTL. Should I instead make a converter? Also should I even be using the GPIO pins of the rpi or…? I see it has analog, R/C, TTL, and PWM. What’s best/easiest for the rpi?
