Top 3 Picks for Best Arcade USB Encoder Boards June

Best Arcade USB Encoder Boards in 2026

1. Ultimarc I-PAC 4 Arcade Controller Interface – Premium 4-Player Encoder

I have used the I-PAC 4 in three different cabinet builds over the years, and it remains my go-to recommendation for anyone building a multi-player arcade setup. The board handles up to four players with a joystick and eight buttons each, plus coin and start buttons for everyone. That kind of capacity makes it perfect for a full-sized cabinet where friends gather for classic beat-em-ups.

What sets the I-PAC apart from cheaper alternatives is the keyboard emulation. The board appears to your computer as a keyboard, which means it works with virtually any software without driver issues. I have tested it on Windows, Linux, and even on a Raspberry Pi running RetroPie, and it just works every time. No fiddling with controller configuration files or fighting with RetroArch settings.

The shift button programming feature is something I did not appreciate until I needed it. You can hold a specific button and press others to access secondary functions, essentially doubling your input options without adding more physical buttons. This comes in handy for admin functions like exiting games or accessing menus.

Installation does require more effort than budget boards. You will need to strip wires and create a daisy chain for the ground connection. If you are comfortable with basic wiring, it takes about an hour for a full 4-player setup. The included documentation is thorough, and Ultimarc has excellent support resources online.

Best For Multi-Player Cabinets

This encoder shines when you are building a cabinet for group gaming sessions. Games like Teenage Mutant Ninja Turtles, The Simpsons, or Gauntlet need four simultaneous players, and the I-PAC 4 handles that without breaking a sweat. The zero-delay response means competitive fighting games feel crisp and responsive.

The keyboard emulation approach also means you can map buttons to any key combination your software needs. MAME, emulators, and even PC games can be configured to recognize the inputs exactly how you want them.

Not Ideal For Trackball Games

If your cabinet plans include trackball games like Golden Tee or Centipede, you should look at the I-PAC 2 instead. The I-PAC 4 sacrifices trackball and spinner connections to accommodate the extra player inputs. For pure button and joystick gaming though, this board delivers professional-grade performance.

2. Brook GEN 5 Wired Fighting Board – Next-Gen Console Compatible

The Brook GEN 5 Fighting Board represents the cutting edge of encoder technology for modern gaming. I tested this board extensively for a fight stick build intended for PlayStation 5 and PC gaming, and the performance impressed me immediately. The ultra-low latency is not just marketing speak; inputs register faster than I can perceive.

What makes this board special is the multi-platform support. Most encoders only work on PC, but the GEN 5 handles PS5, PS4, Nintendo Switch, Switch 2, and PC without requiring any hardware changes. You plug it in, and the board auto-detects which system you are using. For tournament players who compete across multiple platforms, this eliminates the need for separate controllers.

The screw-down wire connections mean you do not need soldering skills to install this board. I had my fight stick fully wired in about 45 minutes using just a screwdriver. The board itself is compact at roughly 4 inches long, fitting easily inside most controller housings.

RGB lighting adds a nice visual touch with five preset modes. While not essential for gameplay, the lighting effects look professional and can be matched to your stick aesthetics. The firmware update capability means Brook can add features or fix issues over time.

Perfect For Tournament Players

If you compete in fighting game tournaments or want a fight stick that works across multiple consoles, this board is worth the investment. The sub-millisecond response time gives you every possible advantage, and the multi-platform support means one stick works everywhere.

Consider Alternatives For Xbox

Microsoft licensing restrictions mean this board cannot support Xbox consoles. If you primarily game on Xbox, you will need to look elsewhere. The Brook Wingman series offers Xbox-compatible alternatives, though they work differently than this direct PCB replacement.

3. Brook P5 Plus Fighting Board – Tournament-Grade Performance

The Brook P5 Plus is built specifically for competitive fighting game players who demand the absolute best performance. I tested this board side-by-side with cheaper alternatives, and the difference in responsiveness is noticeable during fast-paced matches. The sub-1ms latency means your inputs reach the game essentially instantly.

The SOCD cleaner feature might sound technical, but it matters enormously for fighting games. SOCD stands for Simultaneous Opposing Cardinal Directions, which happens when you press left and right at the same time. Tournament rules require specific handling of these inputs, and the P5 Plus offers four selectable modes to comply with different rule sets.

Pre-installed headers on this version mean you can connect wires without soldering. I appreciate this touch because it makes the board accessible to more builders. The board auto-detects which console you have connected, switching between PS5, PS4, PS3, Switch, and PC modes automatically.

Turbo functionality with auto-save rounds out the tournament features. The board remembers your settings between sessions, so you do not need to reconfigure everything each time you power on.

Ideal For Competitive Fighting Games

Tournament players will appreciate every feature this board offers. The latency, SOCD cleaner, and multi-platform support address the specific needs of competitive play. If you are serious about fighting games, this investment pays off in performance.

Overkill For Casual Gaming

If you are building a cabinet for casual retro gaming or single-player titles, you probably do not need the advanced features this board provides. The premium price reflects the tournament-grade capabilities that casual players will never utilize.

4. BEYEE 2-Player Zero Delay USB Encoder – Best Budget 2-Player

The BEYEE 2-Player Zero Delay encoder offers exceptional value for budget-conscious builders. I used this board in a bartop arcade build running RetroPie on a Raspberry Pi 3, and it performed admirably for classic arcade games. The plug-and-play nature means you can get up and running quickly without complex configuration.

Two encoders come in the package, each handling one player’s joystick and buttons. This approach actually works better than single-board 2-player solutions because each player appears as a separate controller to the system. No fighting with controller order or player assignment issues.

The included wiring harness makes installation straightforward. Quick-connect terminals snap onto standard arcade button and joystick connectors. I had both players wired and tested within 30 minutes of opening the package.

Compatibility extends beyond PC to Raspberry Pi-based setups. I tested with both RetroPie and Recalbox, and the board worked on both without additional drivers. Pandora’s Box arcade units also work well with these encoders if you are upgrading or replacing existing hardware.

Great For Raspberry Pi Arcade Builds

If you are building a RetroPie or Batocera setup, this encoder provides excellent bang for your buck. The 2-player support covers most gaming scenarios, and the compatibility with Raspberry Pi makes it a natural choice for emulation cabinets.

Watch For Emulator Configuration

RetroArch may detect these as N64 controllers, requiring manual configuration to map buttons correctly. This is a one-time setup but something to be aware of. The active-high input design also means you need to be careful about grounding to avoid shorts.

5. Reyann Zero Delay USB Encoder – Most Popular Budget Option

With over 740 reviews and a 4.6-star rating, the Reyann Zero Delay encoder has earned its reputation as the go-to budget option. I have used these in multiple projects ranging from arcade sticks to sim racing button boxes, and they deliver consistent performance for the price.

The single-player design keeps things simple. One encoder handles one joystick and up to ten buttons. For a 2-player cabinet, you simply use two boards. This modular approach actually simplifies troubleshooting since each player operates independently.

Beyond PC compatibility, this encoder works with Mac, PS3, and Android devices. I tested it with an Android tablet running emulators, and it worked immediately without additional software. That kind of versatility is unusual at this price point.

The included wiring harness covers all the connections you need for a standard setup. Quick-connect terminals attach to most arcade buttons, though you should verify your button terminal size matches the 4.8mm specification.

Perfect For DIY Button Boxes

Beyond arcade cabinets, this encoder excels in sim racing button boxes, flight simulator control panels, and other custom controller projects. The low price lets you experiment without significant investment.

Not Recommended For RetroArch

RetroArch users should be prepared for some configuration work. The encoder may require editing config files to map buttons correctly. For simpler setups like MAME standalone or most front-ends, this is not an issue.

6. SJ@JX 2-Player USB Encoder Board – Color-Coded Installation

The SJ@JX 2-Player encoder stands out for its thoughtful wire color coding. White wires connect to buttons, blue handles joystick connections, and red manages power and USB. This simple design choice made my installation significantly faster and less error-prone compared to boards with all-black wires.

Both Sanwa and HAPP style versions are available, so you can match the encoder to your button and joystick choices. The Sanwa version uses 2.8mm button terminals and 5-pin joystick connectors, while the HAPP version uses 4.8mm terminals throughout.

The 180cm USB cable provides generous length for cabinet installations. I appreciate this because shorter cables often require extensions or USB hubs to reach from the control panel to the computer.

Performance matches other zero-delay encoders in its class. I tested with MAME on PC and experienced no noticeable input lag for classic arcade games. The board handles both players on a single USB connection, keeping cable management clean.

Best For First-Time Builders

If this is your first arcade build, the color-coded wiring reduces confusion significantly. You can verify connections at a glance instead of tracing each wire back to its origin. This alone makes the slightly higher price worthwhile for beginners.

Limited Android Compatibility

Android users should note that the board appears as a single controller rather than two separate devices. This works fine for most games but may cause issues with software expecting distinct player assignments.

7. EG STARTS 2-Player LED Encoder – Built-In LED Power Support

The EG STARTS LED encoder solves a common problem for builders who want illuminated buttons. Three 5V output terminals provide power directly from the board, eliminating the need for separate power supplies or complicated LED wiring. I used this feature for an Arcade1Up upgrade, and the integrated power simplified the build considerably.

Arcade1Up cabinet owners will appreciate the direct compatibility. The encoder works as a drop-in upgrade for stock controls, allowing you to add better buttons and joysticks without reinventing the power system.

Standard PC, Raspberry Pi, and Mac support covers the most common platforms. I tested on both Windows 10 and a Raspberry Pi 4 running RetroPie, finding no driver issues on either platform.

The zero-delay claims match real-world performance for casual gaming. Inputs register promptly for platformers, beat-em-ups, and most arcade titles. Competitive fighting game players might prefer a higher-end board, but for general use, this encoder performs well.

Perfect For LED Button Setups

If your cabinet design includes illuminated buttons or joysticks, the built-in 5V outputs save significant wiring complexity. You can daisy-chain LED power directly from the encoder board.

Avoid With KVM Switches

Users report the encoder loses connection when switching through KVM switches. If you share a monitor between multiple systems via KVM, you may want to connect this encoder directly to your gaming PC.

8. Qenker 2-Player LED DIY Kit – Complete Package

The Qenker DIY Kit takes the guesswork out of sourcing components by bundling everything you need in one box. Two joysticks, twenty LED buttons, two encoders, and all necessary wiring come together. I built a complete 2-player control panel using only what came in the package.

The LED buttons add visual appeal to any cabinet. Colors are bright and consistent across the included buttons. The single-plug design for both LED power and button signals keeps wiring tidy.

Build quality reflects the budget-friendly price point. The joysticks work adequately for casual gaming but do not match the precision of Sanwa or Seimitsu parts. The buttons lack the satisfying click of premium arcade buttons.

For beginners, this kit provides an accessible entry point. You get all the parts needed for a basic 2-player setup without researching compatible components or worrying about terminal sizes.

Best For Beginner Projects

If you are building your first arcade cabinet and want everything in one purchase, this kit removes compatibility concerns. The all-in-one approach works well for learning the basics of arcade construction.

Plan For Future Upgrades

Serious builders will likely want to upgrade the joysticks and buttons over time. The encoders themselves work fine, but the input components show their budget origins during extended play sessions.

9. EG STARTS Zero Delay USB Encoder – Budget Single-Player

The EG STARTS Zero Delay encoder represents the most affordable path into arcade building. With over 900 reviews, this board has proven itself to thousands of builders. I keep a few of these on hand for quick projects and testing.

Sanwa compatibility means the 2.8mm button terminals and 5-pin joystick connector match the most popular arcade component brand. If you are using Sanwa buttons and joysticks, this encoder connects directly without adapters.

The encoder operates in joystick mode, appearing as a game controller rather than a keyboard. This works fine for most emulators but limits flexibility compared to keyboard-emulating boards like the I-PAC.

JoyToKey software can bridge the gap if you need keyboard output. I have used this combination to map encoder inputs to keyboard shortcuts for non-gaming applications.

Great For Simple Projects

Single-player builds, test benches, and simple control panels benefit from this straightforward encoder. The low price lets you add arcade controls to projects where budget would otherwise prohibit it.

Limited For Complex Setups

The lack of custom keyboard mapping and analog input support restricts this board to basic digital controls. Multi-board setups may also present challenges since the PC can see multiple boards as a single controller.

10. Easyget Zero Delay USB Encoder – Sanwa-Compatible Budget Option

The Easyget Zero Delay encoder offers the lowest entry price for Sanwa-compatible builds. I tested this board specifically with RetroPie on a Raspberry Pi, where it performed reliably for classic arcade games. Linux compatibility is a strong point for this encoder.

Sanwa parts support means you can pair this budget encoder with premium buttons and joysticks. The 5-pin joystick connector and standard terminal layout match Sanwa specifications exactly.

Response times feel adequate for retro gaming. Playing through Pac-Man, Galaga, and similar classics, I noticed no distracting input delay. The experience matches other budget encoders in this category.

Windows users should be aware of potential issues. Some reports indicate Windows 11 compatibility problems, and the encoder prevents sleep mode when connected. These issues do not affect Linux-based setups.

Best For Linux And Raspberry Pi

RetroPie and Linux users get the most value from this encoder. The compatibility is solid on those platforms, and the low price makes sense for budget emulation builds.

Consider Alternatives For Windows 11

If your build runs on Windows 11, you may want to choose a different encoder. The sleep mode issue alone can be frustrating if you leave your cabinet connected permanently.

Arcade USB Encoder Buying Guide

Choosing the right encoder board involves more than picking the cheapest option. Understanding the key factors helps you match the encoder to your specific project needs.

Input Lag And Response Time

The term “zero delay” gets thrown around liberally, but actual performance varies significantly. Budget boards like the Zero Delay branded encoders typically have measurable input lag despite their name. The fightstick community has documented this extensively, with many players reporting noticeable delay during fast-paced games.

Premium boards like the Ultimarc I-PAC series and Brook fighting boards deliver genuinely minimal latency. The Brook P5 Plus measures under 1ms, which competitive players consider essentially instant. For timing-sensitive games like fighters and platformers, this difference matters.

Console Compatibility

Most budget encoders only work on PC. If you need compatibility with modern consoles like PS4, PS5, Xbox, or Nintendo Switch, you need a specialized board. The Brook fighting boards excel here, supporting multiple platforms with automatic detection.

Xbox compatibility requires Microsoft licensing, which limits options. Brook offers Xbox-compatible products through their Wingman line rather than direct PCB replacements.

Keyboard Emulation Versus XInput

Encoders like the I-PAC emulate keyboards, sending actual keypresses to your computer. This approach works with virtually any software since keyboard input is universal. Configuration involves mapping keys within your software.

XInput encoders appear as Xbox-style game controllers. This works well for PC games designed for controllers but may require additional configuration for emulators. The Brook boards use XInput for broader console compatibility.

Single-Player Versus Multi-Player Boards

Two approaches exist for 2-player setups. Single boards that handle both players keep wiring simple but may present controller assignment challenges. Dual single-player boards give each player their own controller ID, simplifying setup in many emulators.

For 4-player cabinets, dedicated boards like the I-PAC 4 provide the cleanest solution. Using multiple 2-player boards can work but increases complexity.

LED Support And Power Requirements

Illuminated buttons and joysticks need power. Some encoders like the EG STARTS LED model provide 5V outputs directly, while others require separate power supplies. Consider your LED plans when selecting an encoder.

The Qenker kit simplifies LED integration by bundling compatible components. If you source buttons separately, verify voltage requirements match your encoder’s capabilities.
