    Super easy for prototyping Pros: Quite easy to figure out without any documentation, all the pins are either well-labeled or obvious. Good quality for the price.Also it is really small so it could be hidden if you wanted to. Cons: None that I can think of... Work right away and compatible with arduino, mbed and all kind of other mircocontroller boards. I don't have any cons till now and I can not think of any. Especially for this price!!! Other: Easy to interface to my Arduino, good deal. I will recommend this to friends. Very cheap, very affordable. Great product for your projects / prototypes. Recommended, GET ONE!.
