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)
