This kit has very high quality of what even if I find it at some retail store, I feel no wonder. One, really just one weak point of this product is, unclear pictures in assembling instruction manual. The enclosure assembling is guided by several pictures in the instruction sheet but they are dark and the object is quite small. Except for it, this kit is perfect for all. I can recommend for everyone!
This is the first of the "really, really tiny" microcontrollers that has actually been useful out of the box. The mechanical design of the shields works well, the mounting kit is ingenious. I cannot wait for the LE Bluetooth module.
