How to Choose the Right South-Facing PCB Keyboard

Selecting the best south-facing PCB keyboard depends on several factors that align with your specific needs and preferences. Here is what to consider before making your purchase decision.

Layout Size: 60%, 65%, 75%, TKL, or Full-Size

Layout size impacts desk space and functionality differently for each user. A 60% keyboard drops the function row, navigation cluster, and numpad entirely, maximizing desk space for mouse movement. This layout suits competitive gamers and users who rely heavily on the center keyboard area. The portable gaming keyboards trend leans toward these compact sizes for travel convenience.

65% and 75% layouts add back arrow keys and some navigation respectively, making them popular compromises. The 75% size keeps the function row while trimming the numpad, which many users find is the sweet spot for both productivity and gaming. TKL (tenkeyless) removes only the numpad, while full-size includes everything for users who need numeric input.

South-facing PCBs appear across all layout sizes now, with 75% being particularly common in enthusiast keyboards. The gasket mount construction pairs well with south-facing designs because the proper keycap alignment enhances the typing feel that gasket builds aim to deliver.

Gasket Mount vs Other Mount Types

Gasket mount construction uses silicone gaskets to isolate the PCB and plate from the case, creating a more flexible typing experience with less case resonance. This results in deeper, cleaner sound and a cushioned bottom-out feel that users describe as “marble-like” or “creamy.” Most keyboards in our recommendations feature gasket construction for this reason.

Top-mount and bottom-mount keyboards transfer more vibration through the case, producing a sharper, more direct typing feel. Some users prefer this for gaming because it provides a snappier response. However, gasket mount has become the enthusiast standard because the typing feel and sound profile are consistently superior for general use.

The trade-off is typically cost, as gasket construction requires more engineering and materials. Budget keyboards historically used plate mount or tray mount designs, but the technique has filtered down to affordable options in recent years. Even budget gasket keyboards like the Ajazz AK820 and GTSP M87 Kit deliver respectable performance compared to more expensive alternatives.

RGB Considerations for South-Facing Keyboards

South-facing LEDs sacrifice some brightness compared to north-facing designs because the light direction faces downward toward the switch stem rather than up through keycap legends. However, this trade-off is worthwhile for most users because the keycap compatibility and typing feel improvements outweigh marginal brightness differences.

Translucent keycaps work particularly well with south-facing LEDs because the light diffuses through the plastic evenly. Side-printed keycaps like the gradient sets included with many Redragon keyboards are designed specifically for south-facing LEDs and look excellent. Cherry-profile keycaps mate properly with south-facing switches without the interference that causes scratchiness on north-facing PCBs.

If maximum RGB brightness is your priority, look for keyboards with north-facing LEDs specifically. Most enthusiasts and keyboard builders prefer south-facing despite the brightness trade-off because the overall typing experience is superior. The difference is barely noticeable in typical room lighting conditions anyway.

Hot-Swap and Customization Potential

Hot-swappable PCBs let you change switches without soldering, making keyboard experimentation accessible to everyone. This feature has become nearly standard in keyboards over $50, though budget options sometimes omit it. If you are new to mechanical keyboards, hot-swappable sockets let you try different switch types without committing to what comes installed.

QMK and VIA support provide deep customization for advanced users. These open-source firmwares let you remap any key, create layers for different tasks, and program macros. The RK Royal Kludge R65 in our list offers QMK/VIA support, which is impressive for a 60% keyboard at its price point.

South-facing PCBs generally provide better compatibility with aftermarket keycaps, especially Cherry-profile sets from GMK, Cherry, and other major manufacturers. This matters if you plan to upgrade keycaps later, as south-facing designs prevent the interference issues that can make expensive keycap sets uncomfortable to type on.
