Hello.
I have seen this bipolar driver from http://mac1.ifrance.com/pap8a/pap8abl/index.htm

I took the liberty to capture the schematic in Eagle and half made the board. I tried to be close to the original board, although the 10 pin header has different layout, I kind of tried to make it more compatible with Pminmo 4 axis board. I think its an interesting drive. See if you can look at it and maybe help out with the board layout.

I am very new to Eagle so bear with me.
In general about the layout, I think half/full jumper could stay on the board. Step/Dir/Enable could go to 10 pin. I add a Wago screw clamp for the external Vcc source, in case you dont want to use the +5v from BOB, although there is space for a 7805 also.
Dont know if Reset is of any use and maybe sync could be wired differently to make it 100% compatible with he 4Axis BOB connector layout.
Dont punish me on the track widths I barely make the routing.
