Quoted from JBK:Why is there a shortage of WPC DMD driver boards. I've been looking for one of the aftermarket boards from Rottendog or XPin. There are zero available from the distributors or manufacture. Why are these not being manufactured?
I may have one if your interested
Though I see Ksarcade has them
