ShadowX75

It is a 75% layout, mechanical keyboard with hot-swap sockets! A rotatory encoder and an OLED screen!

ShadowX75

I made this project because I love keyboards. This would be my second keyboard after a split one! This version runs on QMK firmware and also has a rotatory encoder with an OLED screen

PCB

The PCB is designed to be compatible with Cherry MX switches and features hot-swappable kalih sockets.
