@ccRicers thanks! As far as I know all 7th gen iPads use the same display panel. The one I bought was advertised as compatible with A2200 and A2197 models.
I think this panel size/aspect ratio is about as small as you can get without running in to serious packaging problems (assuming you stick with a mostly unmodified Framework battery). I’ve already resorted to stacking components to make it work in this envelope.
This is really cool man. Love seeing all these stuff that we can do with the Framework.
@ccRicers The iPad 7/8/9 should be using the same LCD panel and digitizers, which fortunately are relatively cheap and available. I’m almost certain that the back case would have to be a custom part since the iPad motherboard is significantly smaller than the framework and the battery interface is completely different, but the idea of using Apple HIDs and displays is really neat and could really up the framework tablet feasibility.
that’s amazing, it would be great to read and learn how you’ve reverse-engineered that.
Thank you! I wish I could say it was some grand adventure with xray machines, decapping, and microprobing, but the reality is far more mundane.
I found a snippet of a schematic in the depths of the internet that showed the pinout. I made some educated guesses about the LED string layout for the power supply design. I have no information on the mating connector, but you can buy no-name parts from eBay or Aliexpress and made up a footprint using calipers and a microscope.
Hi, is there any chance this adapter would work with 12.9" displays?
I have no idea. That will depend entirely on the connector and backlight configuration. There’s no reason why it can’t be modified to work with a different panel (assuming it’s a four lane DisplayPort interface).
Karl it is a nice try. Is there any way to get the adapter board details?
This is impressive. Can I ask what kind of device are you trying to engineer?
Hey there, this is great. this is exactly what i have been trying to do. I am new to this type of thing thought. any chance you can share the pinout?
@Brian_Osborne thanks! I’ve just started a public GIT repo for the project and the design files for this board are the first thing I’ve added. GitHub - basketofkittens/framework701c: Stuffing a Framework mainboard in a Thinkpad 701C chassis
Impressive works. If you don’t mind, can you share about how much the board costed you? I want to recreate something similar myself, and wondering how much making such thing would cost me.
Also, is the board hand-soldered, or ordered to be assembled at the factory?
I paid about 180USD for 10 bare boards from PCBWay (4 layer, 4/4 mil trace/space, 0.2mm min hole). I opted for matte black solder mask and ENIG plating, which drive the cost up somewhat. If you don’t mind green solder mask and HASL plating, the same 10 boards would cost about 135USD.
I hand soldered the board. I have no idea what assembly would cost, as I’ve never used that service.
I ended up looking for panels that can be connected directly to eDP cable because I lack skills and money… Seems like for Thinkpad t21, I can use original framework screen as well, so I’m considering that as well.
My deepest respect for nailing that converter!
@Karl_Buchka
What eDP cable did you use to connect this adaptor board to the Framework motherboard? I was able to find all the other parts to make this design with. Thank you!
Here’s the cable I’m using. Remember that it mirrors the pinout, so you have to take that into account if you’re spinning your own display driver board. https://www.digikey.com/en/products/detail/i-pex/81466-100B-02-D/14312108?utm_medium=email&utm_source=oce&utm_campaign=4251_OCE22RT&utm_content=productdetail_US&utm_cid=3017853&so=76779661&mkt_tok=MDI4LVNYSy01MDcAAAGFjnMUZbhwtRWRHyNfk0D4HEKWZmqM08Hv1J08dFiZMegOscyvfksQVNZAav4uR-bVGFXICCt89xAbuAsB1WiQCTPZZzScLh0nxt5AT2Ez
For others who are interested in reusing iPad displays this might be worth reviewing:
This board is also available if you don’t want to create your own:
@Karl_Buchka I’m sorry for all of the questions, but I ordered the giant 3D printer for my T25 project, but I’m curious about the display cable used in yours. It looks custom–would you mind sharing how you acquired it? I’ve looked for edp cable extensions but haven’t seen any that look good, and I’m afraid that my project might require one. Thank you! 
@Karl_Buchka AGH! I ctrl-F’d here and in the 701 thread but must have typo’d or something. I’m sorry.
You’re a scholar and a gentleman, and I appreciate your help!
