I bought these for an Arduino project. They mostly work as expected. However, the box arrived slightly damaged. One of the boards was DOA and completely nonfunctional (looks like bad soldering on closer inspection). The other one too had a small piece of circuit board hanging off the end, although it was easy to cut off. However, the other 8 were fine and appear to be fully functional after a short test.
