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.
