Talk:Notes on using the OLPC developer boards
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 (U20? numbering unclear)
- 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.
