3G (HSDPA) mod

The 9mm mini PCIe connector alternate Molex P/N 67901-9001 (lead free) is available from www.onlinecomponents.com at $1.26 each, but there is a minimum order of $35.00

Anyone buying $35.00 worth of stuff from this company in the near future?

 

I'm also interested... Still did not find this part in UK...

 

Another alternate part number for this Mini PCI Express connector

119A-92C00-R

9.2mm high.

I requested samples of this number and the Molex lead free P/N. I will wait and see if anyone ships.

 

There is a chap on ebay selling this part.

Quite pricey, but all I could find..he doesn't do the 9.2mm one yet, just this one or a 4mm

I installed the 5.9 mm high connector from mouser.com (P/N 656-MM60-52B1-E1-R)

Had to remove the 3G shelf in the lower case and move it .075 higher, while shaving .075 off both the motherboard and daughter board's mounting bosses. (Very much like plastic model building stuff) It came out nice, but was labor intensive.

Still expecting to receive some samples of the 9.2 mm (P/N 119A-92C00-R) connectors at some point in time. (Edit) got the 9.2mm high connectors they appear to fit fine.

 

My Sim card readers P/N SPPN06A000040 arrived today. Getting closer... (edit) Molex sim reader 475530001 is much thinner then the SPPN06A000040

 

Well it would appear that Molex does make a 9.0mm high mini PCI-e connector.

The new part number is 0483380090, or 48338-0090, it is so new it does not come up in any searches

I got them as samples.

 

Asked for a sample directly from Molex. Spoke to a lady on the phone and they have none anywhere, so they need to make them and the MOQ is 300. Not going to happen...

Search continues.

or £5.99 from ebay

 

Cool, thanks for that.

 

A quick question. Two jumpers need to be installed to route power to the PCI-e connector and the SIM card holder, as tnkgrl explained:

PCI-e jumper
SIM holder jumper

How do you install a jumper?

The only 'jumpers' I've come across before are ones where the pins already soldered to the circuit board and you simply use one of those push-on plastic jumpers to bridge them. Presumably in this case there are no pins to begin with...?

Cheers!

 

Solder a piece of wire between the two points.

 

Hi, hope everyone is doing well.
I have a question here. Does anyone know what the pin 23 does?
When I was soldering the mini pci-e connection, I accidentally ripped the pad of pin 23 off the motherboard...
And I don't know how to fix it... >_<
Will be very appreciated if anyone can give some suggestions...

Thank you.

"PERn0" is a line for the PCI bus. The 3G connector on the AAO does not have any working PCI bus lines, so PERn0 is unused. Just leave that pin disconnected.

Here is a pin out chart, viewtopic.php?f=43&t=13518&p=85007#p85007

 

Thank you very much for the information.
Now I am much happier.
Will work on the sim holder this weekend and see how everything work out

Thanks!

I was soldering the Mini-PCIe connector last night and after getting it looking great, I discovered that the 3.3V and GND were the same. Now, I'm an electrical engineer and I know that something with voltage and something without voltage shouldn't be the same. Since I found the easiest way for me to remove the connector and search for solder bridges was to use the heat gun and aluminum foil trick, I did it. It worked quite well... except that I accidentally lifted two solder pads at pins 3 and 5. These are listed in the pinout for the connector as reserved. I'm wondering if these are necessary or can I leave them alone? I was able to find my solder bridge and correct it, so I'm ready to attempt it again.

Thanks.

You can leave pins 3 and 5 disconnected. The connector will work fine.

Please describe this "heat gun and aluminum foil trick" in detail, sounds like something I might need at some time.

Thanks

 

Thanks. I had just decided to leave them disconnected before waiting for a reply, so I'm glad you said they were unneeded. The aluminum foil and heat gun trick is pretty simple:

1) Take a piece of aluminum foil that is pretty large so as to cover the parts of the board you don't want to heat up.
2) Cut a hole in the foil just large enough for the part you want to desolder including all the pins attached to the part.
3) Use a heat gun first on low, then high (your temps may vary so start low and move up) while holding onto the part with some pliers or vice grips.
4) As the heat melts the solder (it should heat all pins at the same time), apply a slight bit of pressure to remove the part. Be very careful at this point as it can lift solder pads. My heat gun has two settings and on high it only takes a few seconds of heat before the part lifts.

I learned this trick when adding a socketable EPROM to my Directv R10 DVR. You are more likely to lift solder pads, but it can be better than breaking pins the conventional way, so it's your choice what you might want to fix later.

 

Thanks

 

Be careful!. This may desolder the rest parts around. I had used the same method but used also napkins soaked by water on the rest details around and under the aluminium foil . This will keep them cold.
However the best way is to use a professional tool - hot air desoldering station with temperature control.
