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.

Connectors/LEDs

  • CN1: JTAG Connector for Marvell wireless chip.
  • CN2: Old LCD Connector. Definition changing.
  • CN3: External stereo audio line output (switched)
  • CN4: USB
  • CN5: External mono microphone connector (switched)
  • CN6: USB
  • CN7: USB
  • CN8: Mono right side speaker connector
  • CN9: Internal stereo speaker connector
  • CN11: DC input jack (10V-24V; nominal 12V)
  • CN12: CRT
  • CN14: Used for DCON Debugging. Definition changing.
  • CN15: Internal microphone connector
  • CN16: AMD Geode JTAG Connector
  • CN17: Used for DCON Debugging. Definition changing.
  • CN18: CRT/LCD Jumper
  • CN19: Unused
  • CN20: Used for manufacturing (serial Flash programming)
  • CN21: Battery connector (Pin 1: Gnd, 2: VBat)
  • CN22: Battery sensor. Definition changing.
  • CN23: Internal PS/2 Connector to keyboard & input module (Pin 1: TP Data, 2: TP Clk, 3: Gnd, 4: KB Data, 5: KB Clk, 6: Power [3.3V or 5V])
  • CON1: Unused large solder pads (was mini-PCI on pre-A-Test boards)
  • D2: LED. Definition changing.
  • D3: LED. Definition changing.
  • D4: LED. Definition changing.
  • D21: LED. Definition changing. Same output as D3 (front/back view)
  • D22: LED. Definition changing. Same output as D2 (front/back view)
  • D23: LED. Definition changing. Same output as D4 (front/back view)
  • J1: Serial port connector. 3.3V levels. (Pin 1: 3.3V Power, 2: TxD, 3: RxD, 4: Gnd)

NOTE: Just because it doesn't say it's changing above, doesn't mean that it won't change!
