I’ve been thinking of attaching a 5 way tactile switch to my Lets Split and you’re one of the few…

Hi Boon Gan Ng,

You got it, that’s exactly how it works; the 5-way switch acts as arrow keys by default, and becomes a mouse on a second layer. I’ve connected the 5-way switch as if it were 5 different switches: the ground pin is the column, and each direction pin is a different row (you‘ll only need one diode because it’s only possible to activate one direction at a time).

Hope this helps! Check out my repo for more details: https://github.com/w4ilun/pocket-keyboard
