Note : This ReadMe is written by a human known as Hemanth from India, I am new to this and learning every day. Please highlight the mistakes I may have made.
Overview
This is my first Stardance HackClub project. I have officially worked on this project for 22+ hours. I want to thank all the people to who are responsible in creation of these organizations.
Functions
- Modes like Dev, Editor, etc with different presets of keys.
- Contains a satisfying Mini Game. (Discussed in depth in upcoming sections)
PCB Design
I was already well versed with simple hardware projects using Arduino UNO and ESP 8266, but even though I knew about PCBs I never used them as they are expensive. Learning KiCad was pretty straight forward and easy.
Mainly routing was a bit challenging but everything else was easy. DRC have 0 errors except silkscreen warnings.

CAD Design
Cad was one of the field I had zero ball knowledge about. So designing it was fun but also was a pain. Due to daily internet cap I was not able to download Fusion 360, so OnShape was the way to go. The design mainly consists of Base plate with Heatset Inserts and Top Plate with holes for M3 screws. PCB gets sandwiched between. All this was done in keeping +0.2 mm tolerance in mind.

Questions
How big is the MACROPAD PCB?
It measures 95 × 95 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MACROPAD use?
34 parts, built around the 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 damnitzhemanth-oss/hackpad-deck 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 damnitzhemanth-oss before reusing the design.
