Yesterday I received the parts I ordered to @jofemodo (boards and cabling, metalic box was not available at the moment but José Fernando told me this week, most likely, he will receive some). It's not a problem for me soldering components to the circuit board, however I decided to order boards with discretes compenents already installed.
I was so excited with my new musical toy that I couldn't resist the temptation to give a try as quickly as possible. Not having a box around to put all boards together, I decided a big sacrifice was needed. I went to the kitchen and opened the freezer and .......ta-chan!!!....here the result.
I think that following the wiki the assembly is very simple. The pin 1 in the flat grey ribbon cable is coloured in red. In boards 2in1 and controllers the pin 1 is where brown wire is connected.
By the way, I made a small "window" in the base of the box for an easy access to the microSD, as you can see in the last picture.
Of course, it's a temporary assembly but it was funny to find a perfect excuse to taste a delicious Stracciatella Ice Cream....and then to explore my ZBox.
