Hello! This is my submission for hackpad! This was made for Hackpad v1.

Features

4x Neopixels!
A big 0.96" OLED screen
Cool silkcreen art

kmk firmware! Control your mouse with this macropad

PCB

Here are pictures of my pcb:

Schematic	PCB

Hope you like it! I made like 10 revisions.

PS. there is a strict assembly order, dm me (@Cyao on slack) to know it

[x] I ran DRC and there are 0 errors

CAD

Designed using FreeCAD! It was painful. Be glad you have the current guide, I spent 10+ hours figuring out how to do everything correctly (and even like this I still did stupid stuff).

Everything fits together with 4 m3 screws and bolts

Firmware

I wrote the firmware using kmk, you can see it inside the repo. It can be used to control your mouse!

Notes

Making the pad was fun ^.^ but I was just too paranoid that something would go wrong and made 15+ revisions lol. Ended up learning how to use OpenSCAD and FreeCAD.
