btwArch Used AI
btwArch is a custom mechanical macropad designed because I use Arch btw. This hackpad features a sleek design with customizable keys, RGB lighting, and modern connectivity options to enhance your workflow.
Built as part of the HackClub 2025 initiative, this project serves as both a functional tool and a learning experience in PCB design, 3D modeling, and firmware development.
(It was my first HackClub <3)

btwArch is a custom mechanical macropad I developed because—well—I use Arch btw 😄. This project was created as part of the HackClub 2025 initiative and was my very first experience with the club.
The macropad includes RGB lighting, 3 fully customizable keys, and modern connectivity options. I designed the case using CAD tools with a clean, minimal aesthetic and manufactured the PCB with optimized routing and ground planes. For firmware, I used KMK to enable key macros and lighting effects.
Working on this project taught me a lot about 3D modeling, PCB design, and microcontroller programming. It’s been an amazing learning experience from start to finish.
Thank you for the opportunity to be part of HackClub—it was a lot of fun and a huge step forward for me
