Datasheet for TT3240 stepper driver?

I cannot find any information on this stepper driver. Particularly what I’m looking for is which pins are enable, step and direction. Any info appreciated. I’ve been searching a while but I can’t find anything on it.

Proprietary chip I’m guessing?

Hello, one of mine is dead. Did you find some information about this driver ? I’m looking for à replacement…

Many thanks

I didn’t but there’s a post where someone got in touch and apparently managed to get hold of just a single driver chip.
