Centroid Community CNC Support Forum

I am setting up my new Acorn board with a Leadshine compatible servo driver and it seems that thanks to the many resources in this forum and on Youtube I am progressing step by step.
However, for some technical details like input and output pin specification, timing etc. I would like to refer some kind of datasheet or specification.
Is this available anywhere ?
Thanks
Uwe
