VESC 100/250 IO Ports Protection

Howdy, 

Could anyone tell me if  IO ports on the VESC 100/250 are pretty resilient or would i be best to add protection I wouldn't normally with a mass produced controller. For instance I couldn't find a schematic for the 100/250 but the 6.4 doesn't appear to have any discrete components for low pass filtering or static snubbing I would have expected on  AD port/ports, maybe I missed it though. What about other IO. Maybe it's built in these days to micros, my knowledge is a bit dated. Basically just asking if I can avoid any silly mistakes that might wreck the boards IO. I plan to have a 3 meter throttle cable to my POT in the controller for my gizmo. IF needed I can just build an appropriate IO board for conditioning.

Cheers
