Wafer is the custom, ultra-thin mechanical keyboard built on nrf52840, with full NPM1300 integration and (custom spring) PG1316s switches. Built on ultra-efficient Zephyr and ZMK, has an integrated Memory-In-Pixel display, covered in a full CNC milled aluminum case, with only 4-8mm thin.
It also features MagSafe magnets to have compatibility with stands or to snap them together and fit in your pocket.
I designed Wafer to feel like a finished, professional device rather than a typical DIY keyboard,
Reaching this took me endless iterations across hardware design, case prototyping, firmware, and manufacturing, also working directly with Chinese suppliers on custom switches and batteries to fit the thickness and increase battery life whitin my case format
