Hello! This is my custom macropad for hackclub x amd Blueprint
Description
-
This thing is chonky massive(i couldnt fit my wires and my engravings on a small one)
-
I have a 0.91 inch OLED display displaying a hollow knight image, im gonna animate it and put a clock on it later on
-
I got 6 LEDs with RGB
-
I have a rotary encoder which controls my volume
-
I have 9 keys (including the rotary encoder switch)
-
I have a malenia and alaxander engraving on it :)
-
I have two custom keycaps, one being the sekiro death symbol and the elden ring logo.
PCB
schematic
Even though it says MINI LEDs the, footprint is mini E
pcb
The wires look super messy, this is my first time and idk how to make it cleaner.
CAD
This was the most fun part of the entire process, even though it was painful. I used the education version of autodesk fusion for all this.
Firmware
This was by far the HARDEST part of the entire process as it was really confusing ( ive never writen code in C before so i had to learn everthing from GfG, and i took a little bit of help from gemini cuz i didnt understand what to write in the config and stuff for QMK)
I wrote my firmware in QMK and you can find it in the REPO, the fully compiled one in the Production section

Questions
How big is the Macropad PCB?
It measures 84.3 × 91.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Macropad use?
26 parts, built around the 1N4148WT and SK6812MINI-E. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Macropad KiCad files?
From the shangathechild/EldenPad repository on GitHub, at the commit this page was made from: the board is PCB/Macropad.kicad_pcb and its schematic PCB/Macropad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Macropad design in my own project?
Its repository states no licence, so its author keeps all rights: ask shangathechild before reusing the design.
