Dell Axim Connector Pinout
NOTE: The Axim has a compatibility issue with its serial pinout (serial circuitry is powered down when no signal is on CTS!)
For a description of how to solve it, please see http://www.kolumbus.fi/ari.torpstrom/pinouts.htm
Pinouts have been gathered from
-
http://www.bevhoward.com/serial.htm#Axim (serial connector)
-
http://www.fermines.com/Dell%20Axim.htm (connecting a GPS)
and from own experimentation.
Note that the connectors are manufactured by FoxConn, Inc. The part numbers SHOULD be (not 100% sure) QL11203-C631 (http://www.foxconn.com/Search/Show_Product_D_Attributes.asp?P_Type1=Connector&P_No=QL11203-C631) (Connector -> System I/O Connector -> Docking Connector ...)
The 100-pin iPAQ version at FoxConn's iPAQ store costs $10.37, so how much would the 40-pin Axim version cost? $4.14? :-P) But maybe it's better to buy a CHEAP recharger at eBay for a couple $$, since mine also contained a full-featured 40-pin connector...
Also, the DellAximX3 connector is said to be DIFFERENT, and all future Dells will use X3 pinout. :-\
Power adaptor pinout is said to be compatible.
Somewhere within these connections there are rumoured to be USB HOST connections (the Axim has some USB HOST capable IC builtin, so connecting further devices via USB HOST ought to be possible

Feel free to copy this information!! It needs to be spread properly.

| 01 | unknown, almost unused (someone said it's GND (shield), but it's most likely NOT correct: since the Axim inside picture doesn't show the usual ground layer non-connection, but rather a small line connecting to it - it's some DATA signal!), also leads to unconnected test pad on USB charger cable |

It is possible that either 12/13 or 18/19 are connected to USB host D+/D-. MediaQ 1132 has USB host functionality, so it would be strange it the pins wouldn't at least be connected to the expansion connector.
