Getting ready to order parts

I’m back at it, last couple days have been busy… Anyhow I have decided Keya motor but I was not 100% clear on voltage, keya says 12volt or 24 volt? I know I read 24V is better with the phidgets but where are things at with keya? I am assuming 12 so I wont need to worry about a step up converter in my system?
I found the link to order the Keya motor in @andyinv post Keya CANBUS motor - great success, many happy etc
PCB… see if I understand this correctly. For an AIO board I have the option of F9P std or micro and since I do not have a F9P currently I should go with the micro because it is the latest version and smaller footprint, otherwise they are identical. Next the IMU is not “built into the board” as I thought earlier but it plugs into the board in the form of BNO085 and requires no other external sensor or wiring? Last, I believe the KEYA motor has a driver built in so I do not need a motor driver?
