-Finally I spend around one month (only my free time) to prepare a layout design with EAGLE for my second prototype. This time it is all based on SMD components and should be pretty small. The problem now is to find a good company which could etch the board for me. I finally stopped at [http://www.pcb-pool.de PCB-Pool.de] which did the work really good. I had to order there a 1dm^2^  board, so that I got second kit for free. For the etching process, I payed around 50.- Euros. For all the components used on the board, I payed again around 80.- Euros. However I had to order the components of the board in big packages, because this were some industrial components. I've received all of them from [http://de.rs-online.com/web/ RS-Online.de].

If I compute the final material price for one such kit, then we will end up in around 60-70.- Euros, just for the material, which is still ok for a prototype. 
 
 The final 2nd prototype layout is looking like this:
