Converting Internal Keyboard to External Keyboard

evilblob said:

I have recently got my hands on a Top Case with the Keyboard and Trackpad from a MacBook Pro (Mid-2009 or Mid-2010), and I want to use it as an external keyboard if it's possible. So is it at all possible to convert the connectors on the keyboard and/or trackpad to something like USB that will plug into an early 2011 MacBook Pro?

To what end? To me, it makes sense to just use a corded or cordless keyboard that you can just plug in. Taking into consideration the amount of effort and technical prowess required for your planned solution, even a $60 keyboard you just turn on seems like a pretty good bargain.

Not sure how to do that, but it would be pretty cool. Probably pretty expensive though.

I agree that if you can find a way it is a cool accessory. There are some of us that enjoy DIY projects mainly for the process.

The keyboard is probably going to be the easier of the two, since apple offers wired keyboards. I would say unless you can also get the trackpad to work there isn't a compelling reason. Why not try to track down some apple diagnostic documents to see if there are electric schematics in them.

EDIT: I actually would love exactly that for my desktop hackintosh. I always recline back in my computer chair, and would love to have the keyboard/trackpad on my knee or something like that. Of course I would definitely have to include the guts to make it wireless (RF not blutooth).

Apparently its as simple as soldering a usb cable to it. They do it with the trackpad in this video but I think they also mention it works on the keyboard.

Probably - the keyboard and trackpad are run off an internal USB hub...

Did you know you can just buy keyboards?

They openly sell them in stores and everything!

Hi @evilblob, where you able to do something with that keyboard and trackpad? I got exactly the same top-case for free and I would like to convert it to USB. Could you please share your experience with this. Thank you

Hi @eze1981 and @evilblob, were any of you able to do this? I too have an old MBP lying around and can't figure out how to connect it to a USB. The video above is for an older model of the macbook.

Hey!
So i guess no one found a solution for this? Im working on a similar project. Does anyone know what format the keyboard uses? Im trying to put a raspberry pi inside an old macbook pro 2011. Is it maybe possible to solder all the buttons to a micro controller and do a custom setup?
At this point its not about if its reasonable. Its about my personal pride. Ill do whatever it takes.

I found this solution for the trackpad:

AHackPAD

Macbook pro touch pad as a replacement for a normal touch pad on a Hackintosh so you do not need special extensions. The touchpad uses SPI or USB. Keep the CY8C24794 as this is the convert from SPI to USB. You will need to connect TPAD_VBUS_EN on the CY8C24794 (pin 4) to 3.3v as that is the...

I can't help at all if you don't want / can't use an original motherboard. I got a broken 2011 MacBook Pro for very cheap and did that "conversion". Took me a long time because I'm super bad at electronics. Anyways, using the original circuitry, the keyboard and trackpad work as follows for me:

Desktop PC BIOS: Works fine
Windows 10: Keyboard works, trackpad works as a mouse (Windows doesn't recognize it as a trackpad.. so no multi-touch gestures)
Linux (Ubuntu): Keyboard works, trackpad works like a charm including all gestures
MacOS: Keyboard works, trackpad works like a charm including all gestures
Android-x86 (inside a virtual machine): Keyboard works, trackpad works like a charm including all gestures
Android-x86 (from USB stick) and Android 10 phone + Android 11 tablet: Keyboard works, trackpad appears dead

Considering that it only doesn't work in Android (the only use-case I have for it.... if anyone has an idea, please let me know!), it will "probably" work just fine with a Raspberry Pi.

I found someone else doing that with a mid 2012 MacBook Pro (like the guy on hackaday) who described everything in greater detail: https://www.eevblog.com/forum/proje...rackpad-from-macbook-pro-(mid-2012)-trackpad/

If you also get a 2012 MBP that could be enough, if you get a different year model it's probably better to get the schematics online (somewhat easy to find on Google) like I did. Hope this helps you.
