Missing USB cable

The board itself is fine, but my kit arrived without the USB programming cable. I had to buy one separately which was inconvenient.

Good hardware, docs need update

The board works well and feels sturdy. However, some of the software examples were outdated. Once I found the latest SDK, everything worked fine.
