Read a potentiometer continuously? on STM32 and analogRead()

I still can’t understand why it was so cheap, based on the schematics it has the same STM32F405RGT6 chip, same DRV8301DCAR driver, and the same NTMFS5C628NLT1G mosfets as the XDRIVE-S but has a AS5047 encoder for about 20e less

But it’s not available anymore, maybe it was a mistake
The braking resistance was missing although it’s listed
