Bayleaf – Building a low-profile wireless split keyboard
Hey HN, I built a wireless, split, ultra-low profile keyboard from scratch called Bayleaf. As a beginner I learned all things electronics, PCB-building, designing for manufacturing, and many other hardware-related skills to put this together. This case study dives into the build process and of course the final result, hope you enjoy!

In plain words
Bayleaf is a wireless, split, ultra-low profile keyboard built from scratch by someone documenting their hardware journey. The project demonstrates the maker's self-taught skills in electronics, PCB design, and manufacturing. It targets keyboard enthusiasts and makers interested in custom input devices. The standout feature is the ultra-low profile design combined with wireless functionality in a split layout configuration.
