Heya, I'm building my Horizon keyboard (choc), which I printed myself from factory, and just realized Steam Deck trackpad is a perfect candidate as a trackpad for its size.

Since it's already running with SteamOS, I believe Linux kernel drivers should be available, and soon we'll see a lot of replacement/spare parts, so I thought it'd be a great candidate to work with small keyboards.

So I was wondering if anyone around here is crazy enough to try Steam Deck's trackpad as a QMK input device. I believe they'll be sold at ifixit (and I'm sure at Chinese sites soon), so I believe it'd be easy to access as replacements, or as a working module, inside broken parts listing.

Thanks in advance!

If i am not mistaken QMK does not support trackpads. they do support digitizers.

If you can get one that is at most 3x3CM then it might work

Cirque trackpad , which I believe is inside a Steam Controller, is supported. There are projects like this already.

I already hacked a Pro Micro (not enough pins, rewired the matrix, reused LED pins, and freed spi pins for the purpose) and added a pimoroni trackball to one of my keyboards, but I want to try and use a trackpad.

It's made by cirque and there are quite a few builds with cirque trackpads so it's likely possible.

Thanks, glad to know this is made by cirque as well. Hopefully the implementation would be easy. If this part is widely available (and I'm sure it will, very soon) I'd love to have this on one of my custom boards.
