New to this, few question on parts.

hello
Im planing to build a steering wheel from a hoverboard motor, im not really big into sim racing, but i like "car games" and DIY stuff so, this seems perfect to me, im currently building my own multigames arcades so next project most likely will be a steering wheel.

questions
1- im planing to build it with a hoverboard motor, most likely a small one (6"? will buy a used one, other parts may be usefull for other projects) and from many videos i watched i saw people either using the BTS7690 and arduino to drive the motor or the odesc board, whats the diference? pros and cons?
2- to have a few butons on the steering wheel i was planing to use an "zero delay" board that is most commonly used on arcades, but can be used for this project with many buttons and has a usb conection. is there any way to conect it to arduino or other board so i could have only one input into the computer, or its normal to have many input devices (sterring wheel, buttons, gearbox, pedals)
3- either option2 or have a bluetooth minikeyboard or something atached to the steering wheel, how usefull is to have a few buttons on the wheel.
4- for the zero delay board, could i make a contact ring for the usb conection so only 4 rings would be necessary instead one for each button plus ground? how good or bad is a usb connection on a connection ring?
5- i already bought a arduino leonardo "copy" and the bts7690 driver, forgot to buy the encoder but will be buying this weekend, all stuff from aliexpress, does this cheap stuff from china may work as intended.
(im good with eletronics, soldering and know components in general, dont know much about programing, good into computer stuff, some woodworking experience and good problem solver in general)
edit 6 - i have acess to some nice brushless motors from breadmaker machine, they seem to be strong and somewhat small, they also usually go with gears and belt, but they are AC and uses a capacitor (they have 3 wires, almost sure one for each direction plus ground) can this be used in any way?
my initial plan is hoverboard motor, arduino leonardo, bts7690 driver, rotary encoder 1000pr.
any advices are welcome

The SMC3 software will not run on Leonardo. It is very specific with addresses for setting up timers. It does not use much wrt library calls. The advantage of the Leonardo is hardware USB support which you don’t need for this application. For your wheel you probably do.

AC servos are extremely expensive. I would suspect that your AC motors are pretty useless. As for hoverboard motors they probably go one direction really fast. DC motors are relatively cheap to control.

All the sim designs you will find here are either geared or drive a lead screw. At the end you will need at least 30Nm of torque IF the bulk of the weight is supported by a Ujoint. If not then more torque is required.
