Talk:Notes on using the OLPC developer boards

Could somebody complete this (CN10, CN13, CN18, CN21, CN23 need info/confirmation), and move it to the main page? All questions are in italics. Pinout is wanted on a few connectors.

Connectors/LEDs

• All of these numbers are allocated starting top left corner, allocated in scanline fashion.
• The front of the board is the side with the VGA connector and the Geode processor.

Warnings

• Just because it doesn't say it's changing, doesn't mean that it won't change!
• Do NOT confuse J1 with CN9! You will fry the audio!
