The madmodder site has a LOT of info about this controller. Type "DDCSV" into this search page https://madmodder.net/index.php?action=search2

The Chinese developer also supports a very active Facebook group:

Not used one myself but looks pretty handy.

I have a Centroid Acorn and a Newker 990MDCb - the latter is also a standalone controller but a bit higher spec than the DDCSV. https://newker-cnc.en.alibaba.com/pr...60796e50PBulLX

For my Acorn, I have a touchscreen all-in-one PC, although an obvious alternative is a NUC (SFF) PC on the back of a touchscreen monitor.
