SJJX Zero Delay USB Encoder Review: Build a PC Arcade Controller

IntroductionBuilding a custom arcade controller does not have to be complicated or expensive. The SJJX Zero Delay USB Encoder LED Joystick Kit is designed for DIY arcade projects where you want to connect arcade buttons and a joystick to a PC, Raspberry Pi, RetroPie, or MAME-based gaming setup. Instead of buying a complete arcade cabinet controller, this type of kit lets you assemble the controls yourself and create a layout that matches your preferred gaming style.Despite the supplied keyword Wireless broadcast streaming encoder Bundle, it is important to understand what this product actually does. The SJJX kit is a USB arcade control encoder rather than a wireless video broadcasting or streaming encoder. Its primary purpose is translating physical joystick and button inputs into USB controller commands that compatible gaming systems can recognize. That makes it especially interesting for retro-gaming enthusiasts, arcade cabinet builders, hobbyists, makers, and anyone creating a personalized control panel.The zero-delay design is one of the main attractions for arcade gaming. Fast button response matters when playing fighting games, platformers, shoot-’em-ups, racing games, and classic arcade titles. A DIY encoder can also simplify wiring by bringing multiple controls together into a USB-connected interface.

FeaturesUSB Arcade Control Interface: The SJJX Zero Delay USB Encoder acts as the connection point between compatible arcade controls and a computer or supported single-board gaming platform. Instead of requiring a complicated custom electronics solution, the encoder provides a practical interface for a DIY controller.Zero-Delay-Oriented Design: Arcade gaming depends heavily on responsive input. The encoder is designed around quick USB input recognition, making it suitable for games where rapid joystick movement and button presses are important. While actual response can also depend on the buttons, joystick switches, USB connection, software, and host system, the encoder is intended for responsive arcade control.DIY Joystick Kit Format: One of the biggest advantages of this type of product is flexibility. You can decide where the joystick and buttons are positioned, select an enclosure, and create a control panel around the games you actually play. This is particularly useful for custom arcade cabinets and tabletop arcade projects.PC Compatibility: The USB connection makes the kit useful for PC-based arcade projects. Depending on the operating system and game emulator configuration, the encoder can be mapped to the controls needed for a wide variety of retro and arcade-style games.Raspberry Pi and RetroPie Projects: DIY Raspberry Pi arcade cabinets are popular among makers because they allow compact hardware to run classic gaming software. The SJJX encoder can be part of such a setup, allowing physical arcade controls to communicate with the gaming platform through USB.MAME Applications: MAME users often want controls that feel closer to a traditional arcade machine. A physical joystick and button arrangement can provide a more authentic experience than using a keyboard. The encoder serves as the interface that connects those controls to the gaming computer.LED Arcade Controller Support: The kit is marketed for LED joystick and arcade-control applications, making it appropriate for projects where illuminated arcade buttons or related components are part of the design. The exact lighting behavior depends on the components and wiring used in the finished controller.Compact Electronics: An arcade encoder does not need to occupy much space inside a control box. This allows builders to focus the enclosure around the joystick, buttons, wiring, and overall appearance instead of designing a large electronics compartment.

Why a DIY Encoder Makes SenseA complete arcade controller can be convenient, but it may not have the button spacing, joystick position, enclosure style, or number of controls you want. A DIY encoder changes that equation. You can build a controller specifically for your gaming habits.For example, a player focused on fighting games might prefer a traditional joystick and six-button arrangement. Someone building a two-player cabinet may need a different layout with controls distributed across a wider panel. A compact tabletop arcade system may prioritize portability and a smaller control surface.The SJJX kit provides the electronics needed to turn those physical controls into a USB input device. This is particularly attractive for hobbyists who enjoy woodworking, 3D printing, acrylic enclosure construction, or other forms of custom fabrication.Pros & Cons

PerformanceIn a DIY arcade controller, performance is about more than the encoder alone. The complete signal path includes the physical button or joystick switch, wiring, encoder, USB connection, operating system, emulator, and game. The SJJX Zero Delay USB Encoder is intended to keep that chain straightforward by translating arcade-control inputs into USB commands.For classic arcade games, responsive controls can make a noticeable difference. Games with rapid directional changes or repeated button presses benefit from controls that register consistently. Fighting games are another obvious example because timing and directional input are central to gameplay.

Setup is another area where this kit can be useful. Rather than designing a custom electronic circuit from scratch, the builder can focus on installing the arcade controls and connecting them to the encoder. Once connected to the host computer, the controls can generally be configured through the operating system or emulator’s controller-mapping interface.However, users should not confuse zero-delay terminology with a guarantee of literally zero latency. Real-world input timing depends on the entire gaming setup. USB behavior, operating-system processing, emulator configuration, game software, display latency, and the physical switches themselves can all influence perceived responsiveness.For Raspberry Pi and RetroPie projects, the encoder can help bridge the gap between modern computing hardware and traditional arcade-style controls. Instead of using a keyboard or generic gamepad, the builder gets the tactile experience of dedicated arcade hardware.For MAME, the value is similarly straightforward. Classic arcade titles were designed around physical control panels, so a properly assembled joystick and button layout can provide a more natural interface than a standard keyboard.Building Quality Into the Finished ControllerThe encoder is only one part of the final product. If you are building a controller for regular use, spend time planning the enclosure and selecting quality arcade controls. Button placement should allow comfortable access without forcing the hand into an awkward position.Cable management also matters. Keeping wiring organized makes troubleshooting easier and can prevent accidental disconnections. Before permanently closing an arcade enclosure, test every input and confirm that each button produces the intended command in the operating system or emulator.For builders who want illuminated controls, LED components can add visual appeal to the finished project. Just remember that lighting requirements and input wiring are separate considerations, and the exact implementation depends on the arcade buttons and components selected for the build.

Wireless Broadcast Streaming Encoder Keyword ConsiderationIf you searched for a Wireless broadcast streaming encoder Bundle, this product should not be treated as a substitute for a video encoder, HDMI encoder, RTMP streaming device, or wireless broadcast transmitter. The SJJX unit is an arcade USB input encoder. Its job is to interpret physical controller inputs for compatible gaming hardware.That distinction is important when shopping because the word “encoder” can refer to very different types of electronics. Video encoders convert or compress video for streaming and broadcasting, while arcade control encoders translate button and joystick signals into commands recognized by a computer or gaming platform.If your broader setup also includes computer peripherals or docking equipment, you may find this September 2026
