Yes, after playing around a bit with this board, and observing a weird behaviour, a deeper investigation led me to state that one of the small smd 74HC14 ic's was not powered at all, as the positive track was not connected to anywhere due to an error in pcb design. A further look at google confirmed that. A small piece of wirewrapping wire fixed it. Also, an smd resistor under the Estop connector was badly soldered and the contact was not working as expected. Reworked solder on smd.
I did not test it yet, I hope that it will work as supposed to !
Received everything correct and well packaged, sorry for the anxiety I will continue buying.

exactly what I needed. I was hoping for some instructions; I hope that they are on the mini CD (not just drivers)
A very good product for this Money.
