Could somebody complete this (CN10, CN13, CN18, CN21, CN23 need info/confirmation), and move it to the main page?
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!
Back of board
- CN1: JTAG Connector for Marvell wireless chip.
- CN2: Old LCD Connector. Definition changing.
