From the project

A cool looking keyboard

Kryptek is my custom full size (108 key) wireless mechanical keyboard, its built around an Adafruit Feather nRF52840 Express.

so basicaly i wanted a full size board that could work wireles over bluetooth but still be usable as a normal wired keyboard when i need it too, and i wanted to understand the entire thing instead of just putting together a kit.. the matrix, the diodes, the I2C gpio expanders, the battery, the screen, the leds ALL of it, so i designed the whole thing from scratch in kicad and fusion 360 which took a ridiculous amount of time lol
