Samsung Galaxy Tab 10.1 external microSD project
Hi, several of we GT 10.1" tab owners over in the tab specific area are looking into adding a external micro SD to our tabs. I am hoping that we might find some more expertise and input in this section of the forum.
The ongoing thread we are discussing the mod in can be found here: http://forum.xda-developers.com/show....php?t=1600661
, but hopefully we can merge the threads, or somehow keep things straight, but it seems this may be the more appropriate forum section.
Brief recap is that it appears the early/pre-release GT-P7500 had an external SD card. My later model GT-P7510 has the associated area on the MOBO unpopulated. I found the connectors, the OP in the thread found the factory SD card holders. I used my tab for a test, soldered the the connector on, and early indications are it is not functioning. So far I haven't been able to dig back into it, but common consensus is that the unpopulated area near the SD reader connector is needed. I have a lot of experience with simpler analog electronics, and analog design, but to repopulate the needed components with no idea of where to start is beyond the scope of my abilities.
We have the GT-P7500 service manual, at least most of it I think. The MOBO photos in the manual show the area populated, but the photos are to low resolution to gain any useful data. I found some supposedly leaked FCC photos of the tab disassembled pre-release. It also shows the SD card area populated, and this one shows the SD card holder as well, but again low resolution.
Currently we are hoping that maybe the very early HW revisions of the 3g GT-p7500 may have had the SD card area populated, and possibly one of you owners could help us.
If anyone has any input, or can help build the circuit from the ground up I am happy to provide any testing/data/pinouts I can.
On a side note-- does anyone know how many times I can disassemble my tab without ruining the case?
Thanks in advance folks!
