These pages are an attempt to reverse-engineer the properties of the Aladin. Two aspects are considered: the electrical behavior and the transfer protocol. I suggest you read this if you want to design your own interface or wish to understand how all the ones presented on this site work. However, if you only want a working circuit this might not be necessary (*might*, because if you need to debug something you will need the information presented here).

If you want infos about Surface Mount Technology/Devices (SMT/SMD), there's also a little paragraph about this.
