J5, J6 miniPCI sockets
These sockets implement the miniPCI interface.
Please note that the current available from the +5V supply is very limited, and generated very
inefficiently (linear regulator from input supply). +5V should be used as a bias voltage only, not to
power a wireless radio !
J8 Console serial port
The standard PC pinout is used. To connect to a PC, use a null modem or "Laplink" cable.

J9 DC power jack
This is a generic DC jack connector with a 2.1mm center pin. Recommended input voltage is +7 to
+20V. Supply current is about 0.45A at 12V, without any miniPCI adapters.
