Handtops, UMPC - HSDPA on OQO see info

READ about the MINI PCI EXPRESS card being used in the OQO 02
If that is the interface for the WWAN card in the OQO 02 then you can change it out with another card from the same manufacturer for there various HSDPA cards which appear to be the same form factor and voltage! While I am sure one would void the warranty, some might consider this a viable option to get what they want from their OQO 02. This is what I am considering doing plus changing the Hard Drive to the new 64GB solid state drive from Seagate (FASTER than the old 32GB solid state drives)

I titled a topic wrong earlier so I am correcting with this new one.

I can't confirm as having seen it, but every post seems to indicate you need to buy the evdo version to get the antenna and other goods to make the mod.

tnkgrl, I notice your HSDPA card lacks the Auxillary antenna port. My HSDPA card has both the Main and Aux...so I suspect that black wire is the auxillary antenna? Here's the pic I am referring to: link

I see the evdo one has it...at first I thought auxillary was for voice, I wonder what auxillary is for...I kinda thought it was for a larger external antenna such as something advanced if you were to dock it in a police/emergency verhicle so they'd have an amplifier attached to the unit...but now I am thinking it is just two antennas...a lot of evdo devices have dual antennas and the pc card just takes the stronger signal of the two...which seems strange unless one is more powerful than the other and why not use that one as the main. Clueless again.

tnkgrl,

What guage and type of wire did you use for the SIM holder?

Landline telephone wire is 26guage. RadioShack had some 30guage, but that is probably too thin. Cat5/6 wire is probably too thick...hmmm, not sure it matters, but thought I'd ask before I give this a go. I have the same sim card holder as you used.

opps, double post...

*educationk12* the black wire is the main antenna. My HSDPA module only features one connector and I've only attached the aux antenna (grey wire) to it because it was most practical - your HSDPA module features two connectors so you can attach both antennae, and diversity is used to pick the strongest signal between both antennae

For the SIM holder, the thinner the wire, the better - you want to clear the gap between the Model 02's back cover and the Model 02's chassis... I used the wires inside the microphone coax cable around the screen of a broken iBook!

Okay, I'll go buy some 30guage wire...I wasn't sure if it would be too thin for so much data to go through.

LOL these are signals not water flowing

*educationk12*, dude... SIMs are clocked at like 8 MHz and running on like microamps at 5V - any wire will do!

lol, now u know the level of my SIM smarts! I was also worried about thin wires with minimal insulation and signal interference but I guess it doesn't matter. I tend to get carried away...instead of installing regular CAT 5e in my house, I installed Cat 6 Plenum...let's just say I'm ready for my place to turn into a skyscrapper any minute now. Waste of money but it makes me feel fuzzy inside. haha ;o)

Thanks ecsk2 for all the links, but I don't think they give me the answer that I need...

Here is what I am talking about...http://www.flickr.com/photos/tnkgrl/485777061/

Scroll over the picture to where it pops up the words "Connector for Missing SIM holder"

I have the same exact SIM card as tnkgrl has in her iphone and my SIM holder is identical to hers. She chose not to solder to that SIM connector, but I have a ribbon that I can use for that, I just need to know which wire goes where and that oqo sim connector isn't labeled.

Okay, I read back through all of this...the only thing I can find is where tnkgrl writes that she may make a "ribbon" cable made of Kapton tape and ultra-thin transformer wire, but then decides to do the ever so difficult very precise/fine soldering.

I didn't find the answer to my problem, yet but I found something really cool.

Dual-Sim Card...use two phones at once on one mobile phone.

Or the super 16 sim card which allows you to switch from up to 16 different phone numbers which doesn't work with ATT but works with Tmobile.

So here's the picture of a SIM Card. link There are 8 pins go to the top four rows. The bottom row (fifth) has three sections which aren't connected to the 8 pins nor is the center connected.

I really would like to get this to work...tnkgrl, I have another question for you...

How did you figure out where to put the wires in the mini-pci card? That Mini-pci is divided into two sectoins with that plastic divider. On the one side where you have 5 out of 6 of your wires...that section has 8 pins in total....so it seems like that must be the SIM side, yet you put that one wire on the otherside of the divider, which I think is the ground based on the following:

So here's my best guess..based on the 6pin simcard pinout diagram that esck2 posted and the following picture from tnkgrl's flickr link Her current setup has the following.

TNKGRL'S SIM HOLDER (sim pin numbers are based on ecsk2 pinout link)

Top Left GRAY = VCC 3.3v DC (sim pin 1)
Middle Left BLACK = CARD RESET (sim pin 2)
Bottom Left GRAY = Card Clock (sim pin 3)

Top/Right BLACK = GND (sim pin 4)
Middle/Right GRAY - VPP Programming (sim pin 5)
Bottom/Right BLACK = In/Out Data (sim pin 6)

TNKGRL'S MINI-PCI (pci pin numbers are based on looking at tnkgrl's flickr photo and numbered from left to right)

First three pins are not used with the sim holder
PCI PIN 4 VCC
PCI PIN 5 I/O
PCI PIN 6 CLK
PCI PIN 7 RESET
PCI PIN 8 VPP
PLASTIC DIVIDER
PCI PIN 9 GROUND
(the rest of the pins aren't used with the sim holder)

I think I just need to know the pinout for an 8pin SIM card and then look at mini-pci pinout.

The difference between a 6 pin and an 8 pin is it has two Application Specific (AS) pins and is setup like this...but I haven't found a picture that shows a sim card diagramed as to the location of the pin numbers.
1 VCC +5v or 3.3v DC
2 Reset Card Reset (Optional)
3 CLOCK Card Clock
4 AS Application Specific
5 GND Ground
6 VPP +21v DC [Programming], or NC
7 I/O In/Out [Data]
8 AS Application Specific

Application specific...I'm not sure I like the sound of that term....I found one source that says one of the extra pins if for PIN presence detect....which is clearly what I am lacking. apparently there are 7 pin card holders too..fun, let's keep it interesting.

OK, sorry better ask tnkgrl about that yeah.

SIM cards are univeral, even "fullsize" SIM cards (CC size) for other applications use the same layout and could be cut down to 'regular' SIM card size, anyone here remeber GSM phones that took FULL CC size SIMCARDS?

my first few Nokias did

This won't help?

(I would be extremely careful when soldeing this, it can not be TOO HOT, nor risk of shortage between the various connections, this HAS to be done with SMD kind of soldering equipment and pref under microscope)

I would do this kind of soldering under the microscope (I used to do that for 10 years and kept the equipment

)

My problem is tnkgrl's card uses a 6pin sim card and my card uses an 8pin sim card, so the problem is not knowing where to put the wires.
