Choosing among keyboard PCBs, cases & plates starts with a practical question: do you want a component to build around, or an assembled keyboard you can use and customize immediately? The 40 Key Ortholinear Mechanical keyboard - QMK (VIAL) P40v2 linear switches takes the second route, with a compact 40-key layout, wired USB-C connectivity, and switch customization already in place.
Quick verdict
At $60, the P40v2 is aimed at shoppers who want to explore a highly compact ortholinear keyboard without starting from a bare PCB, case, or plate. Its strongest reasons to choose are VIAL remapping, hot-swap sockets, and the ability to switch between configured layouts. The main trade-offs are the used condition, the unusual 40-key format, and the mixed switch setup.
40 Key Ortholinear Mechanical Keyboard - QMK/VIAL P40v2
The assembled keyboard is a concrete fit for someone interested in compact layouts and hands-on customization. VIAL support works through the vial.rocks web interface, and the keyboard is currently configured with Colmak mod DH as the primary layout and QWERTY as the secondary layout. A double tap of the "c" key switches between them, while the layout can be changed through VIAL.
That flexibility comes with a specific limitation: the current switch mix is not uniform. It has 34 linear switches and six clicky switches, so the typing feel may not be consistent across the board. The keyboard is also listed as used, which is important context for a shopper choosing between a ready-assembled setup and a new build.
Who it suits
The P40v2 makes the most sense for someone who already wants a 40-key ortholinear arrangement or is curious about learning one. It also suits users who want to move switches around without desoldering, since all switches use hot-swap sockets. Wired users who prefer USB-C connectivity will find the connection style straightforward.
It is a less natural fit for anyone whose priority is a conventional staggered layout, a full-size key count, or a bare component for a custom case-and-plate project. The listed dimensions-19 cm wide, 7.5 cm long, and 2.5 cm high-also reinforce that this is a small, complete keyboard rather than a standalone building part.
What stands out from the listed details
The combination of QMK and VIAL gives the P40v2 its clearest customization angle. You can alter the layout through a browser interface, and the two configured layouts provide a useful starting point. The couple of RGB LEDs serve both ambient lighting and status-light functions, adding a small visual element without becoming the central feature.
The current 34-linear, six-clicky arrangement is worth treating as part of the keyboard's character rather than assuming a single switch feel. The hot-swap sockets give the owner a direct way to replace or rearrange those switches, but the hardware does not remove the need to decide what switch mix suits the intended layout.
Bottom line
Choose the QMK/VIAL P40v2 if a compact ortholinear keyboard, browser-based remapping, and hot-swap switches matter more than a conventional layout or uniform factory configuration. Its $60 price, USB-C connection, and assembled frame make it a focused starter model for exploring custom keyboard layouts, while the used condition and mixed switches define the trade-off.
