Buying Guide

The most important factor is case and plate compatibility. A 75% circuit board can use different mounting points, screw locations, and layouts, so an incompatible PCB may not fit your keyboard.

• Layout support: Confirm the board matches your 75% layout, including 80 to 84 keys, right-shift size, and bottom-row spacing. A 1.75u right Shift is common, but not universal.
• Mounting pattern: Compare screw holes and mounting style with your case. Some PCBs support tray mount, while others use gasket tabs, top mount, or 8 to 12 specific mounting points.
• Switch compatibility: Choose hot-swap sockets for tool-free switch changes. Check whether the PCB accepts 3-pin or 5-pin MX switches, since 3-pin support may require clipped stabilizer legs.
• Firmware and connection: QMK or VIA support makes remapping easier. Prefer USB-C with a detachable cable, and confirm the board supports your operating system before purchase.
• Price and included parts: Bare PCBs often cost about $35 to $90. Check for stabilizers, screws, daughterboards, foam, and a USB cable, since missing parts can add $15 to $40.

If you cannot have everything, prioritize physical compatibility over firmware features or included accessories.

Frequently Asked Questions

How do I choose a 75% keyboard PCB?

Choose a 75% keyboard PCB by matching its layout, mounting style, firmware support, and switch connection to your case and build plan. Most 75% boards use 80 to 84 keys, but knob, blocker, and arrow-key layouts can change compatibility. Check the product diagram before ordering.

What makes a 75% PCB good for a custom keyboard?

A good 75% PCB supports stable mounting, reliable firmware, and the exact switch layout you want. Look for QMK or VIA support if you want remapping, plus USB-C connectivity and clear documentation for plates, daughterboards, and case screws. Compatibility matters more than extra lighting features.

Can I use a 75% PCB in any 75% case?

No, you cannot use every 75% PCB in every 75% case because screw points, USB placement, plate shape, and layout spacing can differ. Check the listed case and PCB model numbers before buying. An 80-key ANSI board may not fit an 84-key layout, even when both share the same general format.

Are hot-swap 75% PCBs better than solder versions?

Hot-swap 75% PCBs are better for frequent switch changes, while solder PCBs suit permanent builds and custom switch wiring. Hot-swap sockets let you replace switches without soldering, but they add a failure point and may support only 3-pin or 5-pin switches. Choose based on maintenance needs, not convenience alone.

Conclusion

The GTSP M87 Barebones Keyboard Kit is the top choice for buyers who want a ready-to-assemble starting point, not just a loose circuit board. If your priority is easier switch changes, choose a hot-swappable alternative instead, because it avoids soldering when you replace switches. Before buying, double-check the size, case compatibility, layout support, included board quantity, and current price. Also confirm whether the package includes a case, plate, stabilizers, switches, or keycaps, since “barebones” often means several parts remain separate. That can change the final cost and assembly time. Pick the board that matches your intended layout and budget, then confirm its connector and firmware needs before checkout.
