Hi,
there are lots of posts about those boards, they go by different names, Bitsensor, RnR and others depending on who is selling
them. They all have one thing in common.....no manufacturer support.
There are a number of well known, liked, even loved AND most importantly SUPPORTED motion control boards
by US and European manufacturers.
Is the time you are wasting on this board, in view of the work backlog, worth the difference between cheap Chinese and the real deal?
