For most users, there is little downside unless they specifically want a Tsangan or other custom bottom row.
Common Misconceptions About the Apollo 87HL
One of the biggest misconceptions is that the “HL” designation means the PCB only supports a non-standard layout. In reality, the layout depends on the specific PCB variant and the plate you pair with it, not simply the product name. Many custom keyboard enthusiasts mistakenly assume that every Apollo 87HL is designed exclusively for a Tsangan or split-bottom-row configuration because premium custom PCBs often prioritize enthusiast layouts. The latest product specifications, however, show that the 87HL 6.25u model is intended for a standard ANSI bottom row, making it suitable for users who want a familiar typing experience without sacrificing premium features. This flexibility is one of the reasons the Apollo series has become popular among custom keyboard builders.
Another misunderstanding involves hot-swappable sockets. Some builders believe that because a PCB is hot-swappable, it automatically supports every possible layout. Hot-swap sockets only determine whether switches can be installed without soldering; they do not change the physical switch positions or stabilizer locations. Those positions are fixed by the PCB design and the mounting plate. Choosing the correct PCB version, compatible plate, and matching keycap set remains essential for achieving a standard layout.
Building a Standard ANSI TKL with the Apollo 87HL
If your goal is to build a traditional tenkeyless keyboard, the process is relatively straightforward. Start by selecting the Apollo 87HL 6.25u PCB, which is designed around the standard ANSI bottom row. Next, choose an ANSI-compatible plate that supports the same switch and stabilizer positions. Using a mismatched plate can prevent switches from fitting correctly or leave stabilizers in the wrong locations.
Once the PCB and plate are selected, install PCB-mounted stabilizers, insert your preferred MX-compatible switches into the hot-swap sockets, and mount the assembly into a compatible case. Because the PCB supports QMK and VIA, you can immediately customize key mappings, media controls, macros, and function layers after assembling the keyboard. The result is a premium custom TKL that looks and feels like a conventional keyboard while offering significantly more flexibility than most prebuilt models.
Should You Choose the Standard or Tsangan Layout?
The answer depends entirely on your preferences.
A standard ANSI layout is ideal if you:
- Already own standard keycap sets.
- Want maximum compatibility with aftermarket accessories.
- Prefer a familiar typing experience.
- Intend to sell or upgrade the keyboard later.
A Tsangan layout may be better if you:
- Enjoy experimenting with custom keyboard layouts.
- Already own 7u-compatible keycap sets.
- Prefer the aesthetics of a wider spacebar and symmetrical modifiers.
- Frequently build enthusiast-grade keyboards.
For most users, especially first-time custom keyboard builders, the standard 6.25u ANSI layout is the simplest and most versatile choice. It offers the broadest compatibility with keycaps, plates, and accessories while retaining all the premium features that make the Apollo 87HL an attractive PCB for custom mechanical keyboard projects.
Troubleshooting Standard Layout Compatibility
Even when using the correct Apollo 87HL 6.25u PCB, builders can occasionally encounter compatibility issues during assembly. Most of these problems are not caused by the PCB itself but by mismatched components. Before installing switches, it’s worth confirming that your case, plate, stabilizers, and keycap set are all designed for the same ANSI TKL configuration. Spending a few extra minutes checking compatibility can save hours of disassembly later.
Here are some common issues and their likely causes:
| Issue | Possible Cause | Recommended Solution |
|---|---|---|
| Spacebar doesn’t fit | Using a 7u plate or keycap | Install a 6.25u spacebar and compatible ANSI plate |
| Stabilizers don’t align | Incorrect plate or stabilizer type | Use PCB-compatible stabilizers designed for the Apollo PCB |
| Some switches won’t seat properly | Plate and PCB layout mismatch | Verify both components support the same ANSI layout |
| Bottom-row keycaps don’t fit | Wrong keycap kit | Purchase a standard ANSI TKL keycap set |
| VIA doesn’t recognize the keyboard | Firmware not flashed correctly | Update or flash the latest compatible firmware |
Most assembly problems stem from mixing parts intended for different layouts rather than from defects in the PCB.
Best Switches for a Standard Apollo 87HL Build
Since the Apollo 87HL uses MX-compatible hot-swap sockets, you have access to a vast selection of mechanical switches. Your choice depends largely on your typing preferences.

Because the PCB is hot-swappable, changing switches later requires no soldering, making experimentation easy.
Long-Term Benefits of Choosing the Standard Layout
One reason many enthusiasts continue to build standard ANSI keyboards is long-term flexibility. The custom keyboard hobby evolves rapidly, with new switches, stabilizers, plates, and keycap sets released throughout the year. A standard layout ensures your keyboard remains compatible with the widest range of future upgrades.
Replacement keycaps are also much easier to source. Whether you’re interested in Cherry profile, OEM, MT3, DCX, or PBT keycap sets, nearly every manufacturer includes a standard ANSI TKL kit. In contrast, specialty layouts often require additional extension kits that increase the overall cost of a build.
Maintenance is equally straightforward. If a stabilizer wears out, a switch becomes faulty, or you simply want to refresh the appearance of your keyboard, replacement parts are widely available. This convenience makes the standard layout particularly attractive for users who plan to keep their keyboard for many years while gradually upgrading individual components.
