== Bluetooth: PBA31308 ==
Infineon publishes [http://www.infineon.com/cms/en/product/channel.html?channel=ff80808112ab681d0112ab6aac4105c1&showAllDocuments=true&tab=2&ipt=false&documentGroup=db3a304412b407950112b408f713001d this PBA31308 documentation] for the Infineon PBA31308 module RoHS-compliant (Class 2 Bluetooth™) used in gumstix



== Ethernet: SMSC module==
As of the Spring 2007, Gumstix uses the SMSC LAN91C111 ethernet module for the various 92-pin and 120-pin expansion boards. The manufacturer specs for the SMSC module are [http://www.smsc.com/main/catalog/lan91c111.html posted here].



== Wifi: Wistron antenna used for wifi and verdex Bluetooth ==

== Motherboard Connectors ==

=== part numbers for the 120pin connector ===

- The [[120pin connector]] that goes on the gumstix is the part #55686-1274 from Molex.

- the mating connector from Molex is part #54876-1274 (discontinued)

- The new mating connector from Molex is part # 0546841204 


=== part numbers for the 24-pin flex connector ===

FH12A-24S-0.5SH(55) Digikey part HFK124CT-ND

The [[24pin connector]] was added to the verdex motherboard in response to customer demands for a daughtercard on the 120-pin side of the motherboard that provides UART, USB host etc function on the 24pin/120pin side of the verdex motherboard as these functions are normally "60-pin" type functions.

With a flat flex cable, it should be easy to bring those functions from the 24-pin flex connector onto a custom board on the120-pin side of the verdex motherboard in order to reduce the thickness of the board "sandwich".

Additionally, for very simple gumstix implementation scenarios, (e.g. connecting say an I2C sensor to a gumstix), the 24-pin flex connector is lower cost & easier to integrate than the 60- or 120-pin connectors.


Gumstix added the 24-pin flex connector to address several issues:

1) being able to get a console while the motherboard is otherwise in use without the physical limitations of the tweener.

2) USB Host.

3) Battery for RTC.

4) Daughtercards that need a flex connector. 


=== part numbers for the 60-pin connector ===

Hirose DF12D(3.0)60DP0.5V80.

The [[60pin connector]] is 0.5mm pitch and has an interboard distance of 3mm, so working with it really requires using surface mount pads and techniques.
