Overview
Bram's MacroPad is an open-source printed circuit board by qkingsoftware, from the qkingsoftware/hackpad repository on GitHub. It is a 2-layer board of 87.2 × 56.2 mm with 24 parts on 30 nets, routed with 200 tracks and 21 vias.
It is built around the SK6812MINI-E. Its parts include 16 diodes, 6 switches, 1 IC and 1 connector. It belongs with the keyboards and input and lEDs and displays boards and the RP2040 boards of this library.

My design for Blueprints HackPad and my first PCB!
I have designed my own design of the HackPad. I have placed 6 switches, each wired to it's own GPIO pin so it's easier to work with it software-wise. I have carefully read the pinout for the rp2040 and based my connection on the support each pin has. This PCB is focussed on software support, since I love that part the most. I also added an 4 pin male header to later connect the OLED display to the HackPad. This oled display will be used for various types of data. Since I focussed this PCB on software I also chained the RGB-LED's to each other since they would otherwise take up all other pins. Since they should be iduvidually controllable, this is no issue. I have properly grounded the PCB using groundplains to ensure proper functionality. I have tried to size the PCB properly, but this might have been an issue. Its ~87.25mm x 56.24mm. The case that I designed is small and ensures proper acces to all io.
NOTE:
I tried my best, but this is my first PCB. So if there are any issues please tell them and I will try to solve them.

Questions
How big is the Bram's MacroPad PCB?
It measures 87.2 × 56.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bram's MacroPad use?
24 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 Bram's MacroPad KiCad files?
From the qkingsoftware/hackpad repository on GitHub, at the commit this page was made from: the board is Bram's MacroPad.kicad_pcb and its schematic Bram's MacroPad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bram's MacroPad design in my own project?
Its repository states no licence, so its author keeps all rights: ask qkingsoftware before reusing the design.
