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.
