Choose Digi connect EM or Digi connect ME

Hi all,
I am new at digi. I am going to use an embedded Ethernet in one of my products. however, I can not decide which I should use, digi connect ME or digi connect EM? Can any body help me about choosing one of these products?

I would recommend reviewing the product data sheets and use what you require:

Dear charleik,
thanks for your reply. Do you know which of these is cheaper:
digi connect ME or digi connect EM?

Connect ME is cheaper (less functionnalities).
