    Seems YifanLu (of Team molecule) is going to help the scene out even more, He has an idea for replacing the 3G modem in a Vita 1000 OLED model with a SD card adapter. However he needs help raising money for prototyping and development in undertaking this project. He is looking to raise $2374, and the developer has already raised over $1000 at the time of writing this (Update: $3,092 was raised exceeding what was sought.).

    • The Idea
      Vita memory cards are too expensive and it would be nice to be able to use a microSD card. The 3G feature is pretty useless. Combing those two thoughts and I decided "what if we replace that modem with USB storage?" This works because the Vita's modem port is simply a USB 2.0 port that uses the miniPCIe form factor. A hacked Vita running 3.60 has the ability to load custom drivers, and it is just a matter of putting all the pieces together.

      Features

      • At the core of the adapter is the USB2244 chip, which is a SD to USB microprocessor. It is a high end chip (you won't find it in cheap SD to USB adapters) that has good power consumption and a long lifespan. It supports SD/SDHC/SDXC cards.
      • You need to open up the Vita and replace the modem card. This is relatively simple and is akin to changing the battery. You can put in a large microSD card, install it, and forget about it.
      • With HENkaku Ensō, you can use the adapter on boot
      • Because there's extra space on the board, I also added two debug ports that the original modem uses to communicate with the Vita. Using them is optional. Developers and hackers can use this for their homebrew and hacks.
      • All design files, Gerbers, schematics, layouts, BOMs, software drivers, etc will be public and open source. Anyone can produce the board as well as modify it.

    • Your Help
      I am not doing this to make money. You will help fund all the supplies and the development process. I will work on this project on my spare time and your funds will not be towards labor costs I incur (designing, building the prototype, shipping and packing, etc). To be completely transparent, I will break down the supply costs of the project:
      • $89.05: supplies for prototyping (components, solder paste, inspection microscope, tweezers)
      • $13.95: breakout board I designed to test the signals from the prototypes. Design files will also be open source.
      • $15.12: First prototype run. 10 boards unassembled with no special options. Just to test the design.
      • $74.40: Second prototype run. 10 boards unassembled with hard gold fingers and stencil. This will be the "product verification test" and is a small run of production quality boards (for example, gold fingers on the connectors are expensive but required if you want any durability).
      • $100 (maybe): Any additional prototypes. This is in anticipation that there's some major bug found in the second prototype. Up to two more runs with no special options. I hope this won't be the case and my estimates are overly conservative (better to factor in this cost now than ask for more money later).
      • $1830.26: Final production of 100 boards assembled with hard gold fingers. The boards themselves will cost $597 and is mainly because of the gold. The components will cost $539.43 (main cost here is the mechanical microSD card slot and the USB IC). The assembly will cost $693.83 since I don't plan to solder 100 boards on my own.
      • $45: shipping supplies (padded envelopes and ESD safe bags)
      • $207: fees taken by Indiegogo and the credit card processor
      More detailed breakdown of the component and board costs can be found in the BOM spreadsheet that will be released as part of the open source package.

    • Is my Vita supported?
      This adapter will only work for a specific set of Vita owners. You must have a 3G OLED model (typically the model number is PCH-110X) that is running firmware 3.60 or less (in order to use the HENkaku hack, which is required). However, a quick search on Aliexpress shows that Vita motherboards running firmware < 3.60 are on sale for about $25 a piece. So you can always buy one and swap your current motherboard (even if it is a Wifi only OLED model) with it.

    • No Warranty
      I'll be upfront about this so there won't be any confusion later. I am doing this in pursue of knowledge and expect to make no money. Therefore, I can't afford to waste time and money with customer support or technical help. You are expected to know how to open up the Vita and how to install HENkaku and the custom driver (instructions will be provided, but I won't have time to help you individually). Additionally, I cannot vouch for the quality of the PCB manufacturer and assembly service (SeeedStudios). They are the cheapest provider, but not 100% of the boards they send back are high quality. So in a order of 100 boards, I expect maybe 75 of them to be completely functional and 90 of them to be mostly working (maybe insertion will be difficult or maybe a connection won't be perfect). In that case, I will not have any extras to send nor will I be testing each unit before sending it out.

      Please note that when funding this campaign, you are mostly paying for the development and getting a working board would be a bonus. You are not buying a tested and working product.
      However, everything from the software and the hardware will be open source. Once the project completes, anyone can decide to invest the money in mass producing it for sale. If you do so, I don't expect any royalities or anything.

    This is a cool idea, I am delighted as I have an almost new OLED 3G PS Vita here.​

      There are loads of mini pcie accessories. That one I found here (actually found it on a google image search)

      But you will need to rewire it so its got a standard I/O if you want to use that, as I saw Yifan post somewhere that Sony didn't use the port in the normal way.

      I think it would be great to make an adaptor, and not too hard, take a mini pcie ribbon cable, cut it, and join up the wires in the right way for the Vita.

      I bought one of the real ones, once i get it he will have probably finalized alot of the unknowns to where what you are saying can be done. This is some cool work he is doing.

      @DeViL303 the link you give goes to the dual slot card, the pic you posted above is what im looking for so i can desolder that plug and reattach to my one wifi only oled, ive got 2 of the assasins creed models, and a black phat wifi only. Im gonna see if i can get one of them to work with either an already made one like you posted, or have the one duped that yifan is gonna send. The boards are identical on both models, just the wifi is missing that jack the 3g has. It still has all the points on the board though, id like to see if i can use like a franken firmware maybe atreyus to get it to work. Ive already seen s and p running the network operator on a wi fi model

      You don't need a franken-firmware. The usbmc I posted about last night will allow you to load the card. It has already been tested and confirmed working on a WiFi only model using the pinouts to a USB port with OTG USB cards and even powered HDD's have been shown to work. It is a plugin you need. PM me and I can help you with a bit more details that I don't want public just yet.


      EDIT

      BTW my Franken-FW is simply a retail and Test firmware hybrid but with Enso we are able to use the updater from Test/DEX kits. While a full Test FW install is 100% possible DEX simply isn't due to lacking hardware. The problem we face now is Test kits as well as DEX kits once fully installed are useless as they require activation from Sony's dev network. And their CMA client on the PC side calls home to Sony each and every time. If you block it from calling home at least via PC ports it will cease to work so someone will need to reverse the software which I don't see happening anytime soon. Maybe a end user made clone implementation of the dev CMA client is much more likely. But like the PS4 Dev/Test kits there is leaked activation passwords and software if you know the right folks but are closely held so Sony doesn't blacklist all the serials but i know they have them for the Vita as well, its how all these guys keep their Test/DEX kits running longer then the normal 30/90 day renewal.

      Yea, maybe even better would be to just throw a usb slot on it and dremel out the case somewhere to make it work. Hell they even have those lil blu tooth usb jacks, plug that thing in and connect to a hard drive enclosure or a pc. I like that approach even better.

      You should be able to get the socket on its own, so you don't have to desolder it.

      I might try that on one of em, i kinda like the idea atreyu gave me of just using a usb adapter there instead. 2.0 speeds arent great like 3.0, but they arent horrible either. Wouldnt it be cool to remove that worthless olug on the top and put a usb slot there for an enclosure or a reader or whatever, its usb. Thats only if that driver the flow made would or could be adapted. Id love to dig into it more, dont have time, sounds like a nice winter project.

      The driver that Yifanlu already works. A member of GBATemp did the mod and used the plugin he made to get it to read the USB port he installed. It works great using his pinout from the Eagle CAD files.
