Therefore, I keep my attention focused on the immediate next step, and simply hope for the best when it comes to future difficulties and/or costs further down the road. Right now the immediate next step is for me and my PCB layout partner to produce our own layout for the first prototype we seek to build, based on the just-recovered Openmoko one and other available references like the Pirelli DP-L10. This step is pure desk work, i.e., editing design files on a computer with the appropriate software tools, so no money is needed for the project itself at this point - although my family could very much use any help given. After this step is done, the results of it will be publicly released: a PCB design file in a free EDA tool format and a set of gerbers which one can send to a fab to produce a physical board. (In fact, all work is being done in a public source repository, so it's really in a state of continuous release, no need to wait for completion.) Only after the design is complete and we have the gerbers for the first prototype will I start looking into how much it would cost to physically produce that first prototype board from those gerbers. It will probably be several months from now, so hopefully by then my personal/family financial situation will improve (the current hardship is expected to last about 4 months), and I may be able to afford that step on my own - and if not, it'll be time for another crowdfunding campaign then. Speaking of which, are you planning to sell the phones you produce yourself, eventually? Or outsource it? I do plan on offering finished products (initially standalone modems for playful use with laptops etc, and later phones) up for retail sale to end users, but whenever someone complains about my asking price being too high, I'll point them to the freely released gerber, BOM etc files and invite them to try producing it themselves for less.

Hi Spacefalcon, Quoth Spacefalcon the Outlaw: I am overjoyed to announce that the original PCB layout files for Openmoko GTA02 have been located and published. This is fantastic news, I'm very pleased! Where does that leave the indiegogo campaign? Is the money not needed now? Eventually you'll need more funds, presumably, for the production parts of the project. Speaking of which, are you planning to sell the phones you produce yourself, eventually? Or outsource it?

GTA02 PCB layout files found!
Hello Om community, I am overjoyed to announce that the original PCB layout files for Openmoko GTA02 have been located and published. I asked Sean M-P about them in mid-February and he quickly replied that he had no problem with releasing them, but actually *finding* a surviving copy took a bit longer. Finally, early this morning I received a big ZIP from Sean, and the files are now on my GSM mini-Wikileaks central FTP site: ftp://ftp.ifctf.org/pub/GSM/GTA02/GTA02_design_files.zip ftp://ftp.ifctf.org/pub/GSM/GTA02/GTA02-MB-A6.zip The first is the original package from Sean (183 MiB, contains all design files for GTA02 A1 through A6 plus BT and WLAN add-ons); the 2nd is a smaller package (11 MiB) containing just the GTA02-MB-A6 PCB layout in original PADS, Gerber and PDF formats. Hopefully Joerg or someone else with an account on people.openmoko.org can mirror the files there as well. This exciting development eliminates the need for the very expensive reverse engineering option I've been considering for the past two months. I and my PCB layout partner will now start working on our own standalone GSM modem module design based on Om's: most of the design will stay the same, but Om-added 0R resistors at R1003 and R1004 will be eliminated (I believe they were the real cause of the infamous bug #1024), the triband RFFE will be replaced with a quadband one, I'll use a higher capacity flash+pSRAM chip (fits the same footprint) and the module will be standalone, powered by a lab bench power supply emulating the battery, with both Calypso UARTs brought out on headers, plus an on-board SIM socket and a female SMA for the antenna.

gta02 pcb layout
Hi, after years, was for scientific :) reasons wanted to give a new life to the gta02 I own. Opened it, and the usb connector was enough fragile. Tried to resolder it but the pcb couper line broke. Cannot see precisely to which resistor that line connected. So need a very good magnified photo or the pcb.

Re: gta02 pcb layout
hi! that was a lovely quick answer.. .found the schematics, but was not finding the pcb layout. it looks that I broke the one toward the gps unit, that is towards the ground, which is normaly not used... or .. is it used on gta02?
