Know before you buy
No, the Corne MX SMT PCB comes fully assembled and factory-soldered. Because it features hot-swap sockets, you can simply plug in your MX-style switches without needing a soldering iron.
Yes, this PCB is designed to be compatible with most standard Corne (CRKBD) MX-style cases. However, always verify your specific case dimensions to ensure proper clearance for the onboard components.
This PCB is pre-flashed with VIA firmware, which allows you to remap keys and configure layers in real-time through the VIA web interface or desktop application. It also supports QMK firmware if you prefer more advanced, custom programming.
Yes, the PCB includes support for OLED screens, allowing you to display layers, key presses, or custom graphics. Please note that you will need to source the screens and any necessary mounting hardware separately.
No, this specific version of the Corne MX SMT PCB is designed exclusively for a wired connection. It utilizes dual USB-C ports for communication between the two halves and your computer.
The board features both per-key RGB lighting and underglow. You can easily customize these effects, colors, and brightness levels directly through the VIA interface.
