Hi everyone! This is MM Studio, and we are here to bringing our new Class series design:
Class 100

Intro
Since the layout follows a full-size 100% form factor, its design inspiration naturally traces back to one of the pioneers of fullsize keyboards — DEC’s (Digital Equipment Corporation) LK201 , which accompanied various terminals succeeding the VT220.

The "LK201" actually existed in multiple versions. For enhanced aesthetics and distinctiveness, we decided to reference the PC version with its signature PC blocker and legend strip in our final design.

PC Blocker:
Beneath the magnetically-attached PC blocker lies a removable metal legend strip with back light and solenoid buzzer module. Also retains the classic three-key indicator cluster (Num Lock, Caps Lock, Scroll Lock).

Programmable RGB part is embedded beneath the legend strip.
When connected, it activates to simulate vintage keyboard POST lighting effects – naturally, this feature can be disabled via VIAL.

Hot-Swappable MCU Module:
(Discussing to remove this and change to 'Class style' badge or switches according to community feedbacks and CN IC)
The removable MCU module integrates critical components like the PCB's primary MCU. This design allows users to preserve their key mappings when swapping between full plate or half plate build pcb configurations – eliminating the need for firmware reconfiguration.
