Choosing among keyboard PCBs, cases & plates comes down to one practical question: do you want a compact split layout with build flexibility, or a more familiar single-piece keyboard? The Corne V3 Crkbd Split Keyboard PCB Kit is aimed at shoppers who prioritize ergonomic positioning and customization over a conventional layout.
Quick verdict
At USD 92.08, the Corne V3 Crkbd Split Keyboard PCB Kit makes the most sense for a builder planning a 42-key split keyboard and wanting support for both Cherry MX and Kailh Choc switches. VIA firmware support adds a straightforward way to program the layout. The main trade-off is that this is a wired PCB kit for a compact split project, not a finished keyboard ready to use immediately.

The clearest reason to choose it is the combination of a split ergonomic design and dual switch compatibility. Its 42-key arrangement is designed to allow more natural shoulder positioning, while support for MX and Choc switches leaves room to choose between standard and low-profile switch styles. The limitation is equally concrete: the kit's Choc Kit 2 Wired configuration centers the build on a wired setup, and the PCB kit format means you are assembling a custom keyboard rather than buying a complete board.
Who it suits
This kit fits mechanical-keyboard hobbyists who already want a split design and are comfortable planning a custom build around a PCB. It is particularly relevant if you want to use Kailh Choc low-profile switches, Cherry MX switches, or keep both switch paths open while deciding on the rest of the build.
The 42-key layout also suits shoppers who are specifically looking for a compact arrangement. Because the design uses a split format, it is better matched to someone seeking separate left and right keyboard sections than to someone shopping for a standard 60 percent keyboard case or a traditional rectangular layout.
What stands out from the details
- Two switch formats: Cherry MX and Kailh Choc compatibility gives the build a meaningful choice of switch style.
- Split layout: The design targets more natural hand and shoulder positioning and is described as helping reduce hand strain.
- VIA support: The PCB can be programmed with VIA software, which is useful when assigning keys for a nonstandard 42-key layout.
- Build-focused format: The purchase is centered on custom mechanical keyboard components, making it suitable for a project rather than a plug-and-play keyboard.
Meaningful trade-offs
The compact layout is the central commitment. A 42-key split keyboard can be appealing for a minimalist setup, but it also means the build is organized around a smaller, specialized arrangement. The wired configuration is another important consideration for anyone deciding how the finished keyboard should connect.
The USD 92.08 price is best judged alongside the project nature of the kit: the PCB is the focus, while the broader build still depends on the components and assembly choices required for a custom keyboard.
Bottom line
Choose the Corne V3 Crkbd Split Keyboard PCB Kit if a 42-key split design, VIA programming, and MX/Choc compatibility match the keyboard you want to build. Pass on it if your priority is a complete conventional keyboard or a non-wired setup rather than a hands-on custom project.
