Lets start with the initial look at what's in the bag, everything one needs to setup a stepper motor driver, well partly yes but mostly no. 1. The USB cable, another drawer filler as this cable serves no purpose with this kit being a standard A-B USB cable while the UNO has a micro USB-B connector. 2. No Jumpers for setting micro stepping, well being a cheaper kit I didn't really expect these, but it would have been nice to have. 3. The motor drivers and heatsinks, well good luck attaching these as there is no thermal adhesive supplied on the heatsinks, and to make matters worse should one have a little adhesive left from another project there may be fireworks as the heatsinks will short on the surrounding capacitors (I know annodised aluminium is non conductive, but these little heatsinks being so scratched up I would not trust that fact). 4. Random pin header strip, now these are always handy so no complaints at getting a free one. To summarise, this kit could be made actually useful at no additional cost, by replacing the large USB A-B cable with a micro USB, removing the pin strips and adding jumpers, also adding an insulating thermal adhesive strip on the heatsink.
