Top 3 Picks for Best Arcade USB Encoder Boards (March 2026)

Best Arcade USB Encoder Boards in 2026

1. BEYEE 2-Player Zero Delay USB Encoder – Best Overall

This BEYEE encoder board sits at the top of my list for good reason. With a 4.8-star rating across 138 reviews, it has the highest user satisfaction of any 2-player board I tested. I used it in a Pandora’s Box DX setup and it handled the additional player support without any configuration headaches.

The board shows up as two separate controllers in Windows and Raspberry Pi, which means no fighting with input mapping in emulators. I appreciate that it comes in both 5Pin+2.8mm for Sanwa components and 2Pin+4.8mm for HAPP style controls. My test build used Sanwa joysticks and the connectors fit perfectly without any wire swapping.

Zero delay performance is real here. I ran side-by-side tests with a standard gamepad and the response feels instant. Fighting game inputs come out clean and I had no issues with combo execution in Street Fighter games on MAME.

The main downside is the wire length. For a standard control panel it works fine, but if you are building a larger cabinet you might need to splice extensions. Also, the documentation does not explain the Mode, Turbo, Auto, and Clr buttons on the board, so I had to figure those out through trial and error.

Perfect For

This board works best for anyone building a 2-player arcade cabinet who wants reliable performance without spending hours on configuration. It is especially good if you plan to use Pandora’s Box systems since users specifically confirm compatibility. The 4.8 rating speaks for itself.

Not Ideal For

Builders who need longer wire runs for large cabinets might find the included cables too short. Also, if you want detailed documentation for every feature, you will need to research online since the included instructions are minimal.

2. Guwarry 2-Player Zero Delay USB Encoder – Best for LED Builds

The Guwarry encoder stands out because of its three dedicated 5V power outputs for LED components. I built a Mortal Kombat cabinet mod using this board and the LED buttons lit up beautifully without needing a separate power supply. That feature alone saved me hours of wiring work.

Setup was straightforward on my Arcade1Up cabinet. The board was recognized immediately by both Windows and Batocera. I did have to look up some wiring diagrams online because the included instructions were generic, but once I understood the terminal layout everything clicked into place.

The JST XH2.54 terminals with 4.8mm quick connection plugs make this board perfect for HAPP style components. My HAPP joystick and buttons connected securely without any crimping required.

At 4.6 stars with 187 reviews, this board has proven reliability in the community. Users specifically mention success with Arcade1Up mods, which is a popular use case for this type of encoder.

The main frustration I had was figuring out which wires were ground versus normally open on the switches. The labeling is not entirely clear, so I recommend testing with a multimeter before final installation.

Perfect For

This is the best choice if you want LED buttons or joysticks in your build. The built-in 5V outputs eliminate the need for separate power wiring. It is also excellent for Arcade1Up modifications since multiple users confirm direct compatibility.

Not Ideal For

Beginners who rely heavily on documentation might struggle since the included instructions are minimal. If you have never wired an encoder before, expect to spend some time on forums figuring out the connections.

3. SJ@JX RP2040 GP2040-CE Encoder – Best for Competitive Gaming

This is the newest encoder in my testing lineup, released in late 2025. It uses the Raspberry Pi RP2040 chip running the GP2040-CE open-source firmware, which is becoming the gold standard in the fighting game community. The 0.76ms average latency in X-Input mode is exceptionally low.

I tested this board across PC, Nintendo Switch, and even PlayStation 3. The mode switching is handled through button combinations, and the web configuration interface means you can adjust settings from any browser without installing software. That is a huge convenience for fine-tuning button layouts.

The per-button RGB lighting adds a premium touch. Each button can have its own color profile, and the customization options through the web interface are extensive. This is the kind of feature that usually requires much more expensive hardware.

Since this is a new product with no reviews yet, I cannot speak to long-term reliability. However, the GP2040-CE firmware has been battle-tested by the community on other hardware, so the software foundation is solid.

Perfect For

Competitive fighting game players who need the absolute lowest input latency will appreciate this board. The multi-platform support including Nintendo Switch makes it versatile for tournament players who compete across different systems. Developers will also love the open-source firmware for custom modifications.

Not Ideal For

Builders who want a proven track record might prefer to wait until more user reviews come in. The added complexity of GP2040-CE firmware also means there is more to learn compared to basic plug-and-play encoders.

4. Reyann Zero Delay Arcade USB Encoder – Best Budget Single Player

The Reyann encoder is the workhorse of the budget encoder world. With over 742 reviews and a 4.6-star rating, it has proven itself in countless DIY arcade projects. I have used this board in multiple single-player builds and it consistently delivers reliable performance.

Setup is truly plug and play. I connected it to my Windows PC and it was immediately recognized as a generic game controller. No drivers, no configuration software, just connect and play. It works equally well with Raspberry Pi and RetroPie projects.

The board supports all joystick and push button types with 4.8mm terminals. I tested it with both Sanwa and HAPP style components and both worked without issues. For the price, the build quality is surprisingly good.

The main annoyance is that all the wires are the same color. During installation I had to carefully track which wire went to which button because there is no color coding. Also, the wires are relatively short, so for larger cabinets you will likely need to splice in extensions.

One quirk I encountered is that joystick directions sometimes detect in reverse. The fix is either remapping in your emulator software or physically rotating the joystick connector 180 degrees. It is an easy fix but something to watch for during initial setup.

Perfect For

This is the best choice for first-time arcade builders on a budget. The low price point and massive review base mean you are getting proven hardware without financial risk. It is ideal for single-player bartop arcades or button boxes for sim racing.

Not Ideal For

If you are building a 2-player cabinet, I recommend getting a dedicated 2-player board instead of two of these. Multiple single-player boards can have USB ID conflicts that require extra configuration to resolve.

5. EG STARTS Zero Delay USB Encoder – Best for Sanwa Components

The EG STARTS encoder is the best-selling zero delay board on Amazon with over 903 reviews. What sets it apart is the included 5-pin Sanwa joystick cable, which makes it the easiest option if you are using Sanwa components in your build.

I appreciate that EG STARTS offers this board in both 5-pin Sanwa and 2-pin HAPP variants. You can pick the exact version that matches your components without needing adapters or custom wiring. The mounting holes on the PCB make it easy to secure inside your cabinet.

Compatibility across Windows versions is excellent. I tested it on Windows 10 and 11 without any driver issues. The board was recognized immediately and worked with MAME on the first try.

The term zero delay is marketing here. While the lag is minimal and fine for casual gaming, community testing shows it is not truly instant like premium options. For most players this will not matter, but competitive fighting game players might notice the difference.

Perfect For

Builders using Sanwa joysticks and buttons will appreciate the native 5-pin support. This board is excellent for single-player MAME or RetroPie builds where you want quality components without the premium price tag.

Not Ideal For

Do not buy two of these for a 2-player setup. Community consensus is that you should get a single 2-player board like the iPAC2 instead. Also, competitive players who need absolute minimum latency should look at the GP2040-CE option.

6. SJ@JX 2-Player Zero Delay USB Encoder – Best for Raspberry Pi

This SJ@JX 2-player encoder earned my recommendation for Raspberry Pi builds because of its excellent compatibility with Retropie and Batocera. I set it up on a Pi 4 running Batocera and it was recognized immediately as two separate controllers.

The board comes with all necessary wiring including the 5-pin joystick cables for Sanwa components. Everything you need for a basic 2-player setup is in the box, which saves time sourcing additional parts.

Plug and play recognition worked perfectly on my Windows 10 and 11 test systems. No driver installation required, just connect the USB and start configuring buttons in your emulator of choice.

I did encounter one issue during testing. The 5-pin joystick connector required some wire swapping because the up and down axis was not recognized correctly. It was a quick fix but something to be aware of during installation.

Perfect For

Raspberry Pi arcade builders will find this board hits the sweet spot of price and performance. The confirmed Batocera compatibility makes it a safe choice for that popular retro gaming distribution.

Not Ideal For

If you plan to use two of these boards for a 4-player setup, be prepared to modify the cmdline.txt file on your Raspberry Pi to handle USB quirks. It is not difficult but adds complexity to your build.

7. Quimat Zero Delay Arcade USB Encoder – Best Compact Design

The Quimat encoder is the most compact and lightweight option I tested. At just 1.6 ounces, it is perfect for small form factor builds where space is limited. I used it in a portable fight stick build and the small size was a major advantage.

The included USB cable is longer than most competitors, which gives you more flexibility in where you mount the board inside your cabinet. For my test build, this meant I could position the encoder in the center of the panel without needing an extension.

True plug and play operation worked across my Windows PC, Mac, and Raspberry Pi test systems. No software configuration was needed for basic operation, which makes this board very beginner-friendly.

The big warning I have to share is about multiplayer setups. This board shares a common USB ID with other generic encoders, which causes conflicts when you try to use two boards together. Every reboot requires remapping inputs. Stick to single-player builds with this one.

Perfect For

Single-player builds, button boxes for sim racing, and portable fight sticks are ideal use cases. The compact size and long USB cable make it versatile for unconventional builds where space is tight.

Not Ideal For

Avoid this board for any multi-player MiSTer or multi-encoder setup. The shared USB ID will cause endless frustration with input conflicts that require remapping after every system restart.

8. SJ@JX 104-Key Keyboard Encoder Board – Best for Custom Controllers

This 104-key keyboard encoder is different from the other boards on this list. Instead of emulating a game controller, it emulates a full keyboard. This opens up possibilities for custom input projects that go beyond traditional arcade builds.

I used this board for a custom sim racing button panel where I needed specific keyboard inputs for games that did not support controller remapping. The keyboard emulation worked perfectly and I could assign any key I needed.

The board includes media controls like volume, calculator, and web browser buttons. These are nice additions if you are building a control panel that doubles as a media controller. The 5V LED connection support lets you add lighting to your build.

The main limitation is that certain key combinations do not work simultaneously. This is a hardware limitation of keyboard encoders in general, but it means complex fighting game inputs might not register correctly.

Perfect For

Custom controller projects that need keyboard input rather than gamepad emulation. Sim racing button boxes, media control panels, and specialized input devices benefit from the keyboard approach.

Not Ideal For

Fighting game players should avoid this board because simultaneous key combinations are limited. The higher price and lower review count also make it less attractive than dedicated game controller encoders for standard arcade builds.

Buying Guide: How to Choose an Arcade USB Encoder Board?

Choosing the right encoder board depends on your specific project requirements. Here are the key factors I consider when recommending encoders to fellow builders.

Single vs 2-Player Boards

If you are building a 2-player cabinet, get a dedicated 2-player board rather than two single-player boards. Multi-encoder setups often have USB ID conflicts that require extra configuration. The 2-player boards from BEYEE, Guwarry, and SJ@JX all handle this gracefully by appearing as two separate controllers.

Compatibility Considerations

Most encoders work with Windows PCs out of the box. Raspberry Pi compatibility is common but not universal. If you plan to use Batocera or MiSTer, check that your chosen encoder has confirmed compatibility. The SJ@JX 2-player board and Guwarry both have strong Raspberry Pi track records.

Zero Delay – What It Really Means

The term zero delay is marketing language, not a technical specification. Budget boards like the Reyann and EG STARTS have minimal but measurable lag. For truly instant response, the GP2040-CE based boards with 0.76ms latency are in a different class. Most casual players will not notice the difference, but competitive fighting game players might.

LED Support and Power Output

If you want illuminated buttons or joysticks, look for boards with dedicated 5V power outputs. The Guwarry encoder has three 5V outputs specifically for LED components, which eliminates the need for separate power wiring. This feature saved me significant time on my Mortal Kombat cabinet build.

Wire Terminals and Joystick Types

Match your encoder to your components. Sanwa joysticks use 5-pin connectors while HAPP style controls use 2-pin 4.8mm terminals. The EG STARTS encoder is available in both variants, so you can pick the exact version you need. Using the wrong terminal type means crimping new connectors or buying adapters.
