My surplus source has the UCN5804 in stock. I'm waiting for a reply with prices. I know I'm going to get a batch of these babies. I know unipolar steppers are on their way out, but there are still a lot in circulation. Robert :) Is the obsolete Allegro UCN5804 unipolar driver that difficult to get these days?
