6.5 USB HOSTs
The USB hosts (and wireless connectivity option) are controlled by a single chip (GL850G).
The big advantage of having USB hosts available over USB devices is that you can as well use
them as masters.
The signals follow the familiar and standard USB host pattern:
USB 2-level host

6.6 PWR Jack
Our boards usually use a DC barrel jack with a 2.0mm thick inner pin. The outer hole diameter is
6.3mm. The standard power supply jack used in most of the OLIMEX boards has positive voltage
in the inner pin. You should provide between 6 and 16 volts @ 1A to the board.
