The board seems to work! It drives steppers and behaves normally, I have yet to try the I/o's
I contacted the seller via Ebay. They say the seller has agreed a refund and have advised me to return the board to China!!!!!!! even although I purchased it from a supplier who is less than a hundred miles from me in UK

I have a real issue with this, I feel I should be able to return it from whence it came and get my money back within a couple of days rather than wait weeks perhaps.!!!!
Question I have is this, how much better is a real , smooth stepper board going to be. What are the advantages ?
I'm sorry to boar you guys but I'm just sounding off in the hope that others don't get duped as I did.
