Stepper motor driver - wiring digarm

I've bought one of these off e-bay

**LINK**

It's arrived, but no wiring diagram. I can work out the motor connections, and I might work out the inputs, but no idea what the various switches do. I guess the red block sets the microstepping, but no idea on 3 black ones. Anyone got any ideas?

I've tried and failed on google, and have messaged the vendor

Duncan,

Please forgive me for stating the obvious [especially if I'm wrong] but it all appears to be printed on the board.

P.S. ... Looks a nice board, at a great price ... hope it works well.

This might help:

It looks like the three black switches plus the first red one set the drive current.

Red 2 is the hold current between moves

Red 3/Red 4 appear to set the microstepping level

Red 5/Red 6 decay, presumably how quickly the current decays to the hold level.

Hi Duncan,
This board looks the same as the one I used on my rotary table. My board was clearly labled like the one in the picture on the ebay advert that is in your link. Here is a link to some information that shows the labels if they are missing on your board.

Les,

Thanks chaps, Sometimes one can really ask a silly question, as MichaelG and LesJ say it's printed on the board, but you need a very bright light to even see there is something there, never mind read it. I hadn't spotted it. The link from Russel is much more helpful.

Thanks again

I used the same as Russel's link with an identical driver controlled by an Arduino Uno for a rotary table.
