TMC2240 upgrade (maybe)

[Neumi]

has higher output current and voltage, very compatible to tmc2209

Has even more advantages which could help improve the controller over all. For example Step detection prior to your magnetometer detection on the shaft.
Edit: StallGuard was the word I was wishing my brain could produce.

I think so too. But I have to read a bit more of the datasheet. But I think its very advanced and might be a good replacement for the tmc2209. They're just bringing out too many new fancy controllers too fast :D
