The board is great however the documentation is horid ,when you photograph a circuit board please shoot the top and the bottom as most of us do not care what the side angle looks like,If a wiring diagram is available than show it as it is very important as an engineer or technician will need to know what goes where and we do not need to be confused about a jumper that does not exist. Thanks for the superperson delivery system you have ,I really love it ,I know its hard for a non techie to try an explain what something is that they have no use for and if you need help please call me (after 12pm days) you have my phone number I will be glad to help. please keep up the great job you are doing with sales/delivery .THANKS WCH

These allowed me to prototype a cnc controller using a cheap motor driver. Awesome!

It works as advertised. Although I used 12vdc Vin instead of the 9v, worked just the same.
