Very useful little thing.

Well built, easy to use. It was much smaller than I expected which is great, I like how compact it is. The only negative aspectI can think of is that the Micro USB port does not seem too durable, I-ve seen those rip out of boards all the time. On the plus side, the board offers a couple of well separated and polarity marked pads so you can solder a 5v supply to it if you do not want to use the MicroUSB or if you snap it off. It needs a load to function, a resistor works fine, you may need a 7ish ohm resistor for it so some assembly is required.
