I have three of these stepper drivers. They came in a box with three Pacific scientific Max Drive II 65 volt DC stepper motors. There are no markings on the board that would give away the model. I've spent hours searching Google image search eBay and all over the Internet to no avail.https://uploads.tapatalk-cdn.com/201...bbcbc9417e.jpghttps://uploads.tapatalk-cdn.com/201...07fc3ca1d6.jpghttps://uploads.tapatalk-cdn.com/201...2f5c9e432b.jpg
