No, the gate drivers would be overkill as they add isolation and power switches.
The Skypers need 0/15V drive signals while the main board provides only 3.3V. So you will need to do some level shifting either with an IC (don't know which one) or some simple PNP transistors. Emitter to 15V (you have to generate 15V anyway for powering the drivers), base to main board via 10k resistor, collector to skyper input with 1k pull-down resistor.

The v3 board does not include gate drivers. You'll need to figure out some sort of output scaling to deal with that.
It looks to me, upon checking the Skyper32 datasheet, that they just need 0v - 12v inputs.

So maybe you can figure out some sort of buffers for that, maybe a ULN2003 and pullups?

Hi! I have some questions about V3 mainboard. I want to use 5v hall throttle but board only seems to support 3.3v max input so I think I need to use arduino to convert hall throttle 0.8v-4v signal to 0-3.3v. Also is it possible to use hall sensors like in hub motors 3pcs as motor encoder?

Just put about 10k in series with your throttle signal, that will divide it by 2

Any recommendation for isolate Gate driver module that ready to use with V3 borad ?
