The Chinese website does not say much except for the picture. Because I wanted to find more details about this device to use it in one of the classes I teach gratis in a high school, I bought one of these. That is why I know about the ecellent book, etc. The kit uses an ATMEGA8 and has a USB breakout brick. It even gives a short description of the Arduino IDE. It is ideal for middle school/high school teaching. It shows how to put together a 12hr/24hr alarm clock (you can download the Arduino code from a website they give you in the book) as well as how to use an IR range brick (included). It is different from your unit in that everything is done on a solderless breadboard. This unit is strictly for teach, and you can add other stuff to it. The only similarity with your unit is the alarm clock. By the way, your unit sounds super and I will definitely buy one. Good luck with it.
