That looks bad.
It's a seller from China who has used some translation program to make his offer in German words, but that's about all, because you can't say these are sentences in German.
There's absolutely no hints to the pinout let alone any way of how to drive it.
Only chance you've got i'd say is to mail that seller and pray for a decent answer if any at all.
You shouldn't expect too much effort for a total of 52 euro's of merchandise from him.
Do you have any photo's to upload, showing both sides of the PCB and any text on it ?
