Assembly
This was my first somewhat complex pcb build along with my first time using CAD.
I've not made (gpt'd) the firmware completely and ill set it up completely when the macropad is physically present.
Features
- 8 degree incline
- Oled panel
- Rotary encoder for volume/brightness/etc
- 3 function layers (the 3 right keys)
PS: i had to compromise on the switching functionality of the RE because i couldnt accomodate the its pins due to insufficient gpio pins in the MCU. didnt want to compromise the design and decided to go ahead with this.

Questions
How big is the Macropad PCB?
It measures 88 × 78 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Macropad use?
15 parts. 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 Midaah-r/macropad 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 Midaah-r before reusing the design.
