Where to find training on thingworx architecture etc....

Hello,

Please accept my apologies if it's a very basic question. Can someone please point me to some references or tutorials where I can learn about thingworx architecture and how it internally works, not the mashups and all. I had already gone through mashup related training. Some training which can help me to understand how do I connect my Arduino or Pi via thingworx etc..

Thanks in advance!
