Well, TODAY i have the first board hashing!! NOW i'm very happy.
Now i found my problem: this setup do NOT WORK with the RASPBERRY PI B+. You need to use the Raspberry Pi 2 instead...
And finally, the pins are:
1 is RX
2 is TX
5
4 GND <-- This is the correct.
6 Board Reset
Thank you very much for all your work; with my free-time i did not could install the rpi2 adapter propelly.
