Where are the specifications for the rest of the connectors on the board?
The only two I've discerned from the Wiki so far are the obvious ones:
* IO for serial breakout (J1)
* CON_ANT1
* CON_ANT2
* USB: CN4, CN6, CN7

Some of the development board photos show PS keyboard/mouse wired in, where would those connect?
To CN23 - the pinout is shown below.

Could somebody also identify the connector type for the antenna?
These are U.FL connectors.
