1 axis tb6560 any good?

I have 3 of these but not tried them yet.
They were bought for a very simple application so I'm hoping they will be OK.

Only problem I can see at the moment is they need 5V and return step and direction to the controller.
My application sends step and direction out at 5v and returns to ground.

Being a big hammer man as opposed to MiG welding IC's onto circuit boards i believe you can reverse this with pull up / down resistors ?

Yeah. I hope this one's going to be OK too.
This one seems to repeat the error of deriving the 5v supply from the motor supply. It appears the TB6560AHQ is easily smoked if the motor voltage is applied before the 5v has settled or removed before the 5v is removed.

I suspect the design may be using the optos connected active low to alleviate their slew rate problems rather than using a Schmitt Trigger. At this stage it seems the I/P and driver are completely opto-isolated.

More to follow after I get some juice on it.
