About the project
It has 21 keys, and its connectivity is through Bluetooth.In the design, you may see that there is no sign of the battery. This is because the Xiao already has an SMD space for connecting the battery, so I do not need to connect it to any pins.
Why I made this
I have made many small macro pads consisting of 4-6keys, but this time, I wanted to go big with 21 keys. Also, this one is going to be connected via Bluetooth, giving me a huge relief from wired macro pads.Challenges faced
Although there were no major problems or challenges, while making its case, I had to change the measurement of the top part twice to make it match the bottom part.Also, I had to put the 3d model for each key manually in the KiCad PCB editor, along with removing the silkscreen of each key. This was a tedious task, but I did it :)

Questions
How big is the Veekos PCB?
It measures 83.7 × 141.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Veekos use?
47 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 Veekos KiCad files?
From the LegendPlayz83/Veekos repository on GitHub, at the commit this page was made from: the board is PCB/veekos.kicad_pcb and its schematic PCB/veekos.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Veekos design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
