a split keyboard with legendary layout
This consist of two pcbs: a switch board and an IO board.
The switch board is fitted with an O-ring to provide a soft feel and to seal the board for high-pitched sound damping. To maintain this flexibility, the two boards are connected by a flexible flat cable (FFC).
And the aluminum case is also 5° tilted and 5° tented, providing a more ergonomic typing posture.
Communication between the left and right side uses a Type-c cable.
