Upgrade your DCC installations with NixTrainz Decoder Buddy, the industry-leading 21-pin motherboard system that makes decoder installs cleaner, easier, and far more reliable. At Fusion Scale Hobbies, we carry the full range of Decoder Buddy products, including the Decoder Buddy V5, V5B, Mini, and multiple output configurations designed for HO scale locomotives, steam models, rebuild projects, and sound decoder conversions. Whether you are installing ESU LokSound, LokPilot, SoundTraxx Tsunami2, Digitrax, or other 21-pin decoders, NixTrainz Decoder Buddys streamline your wiring and provide a professional-grade foundation for any DCC upgrade.
Decoder Buddy boards replace messy point-to-point wiring with a clean, organized motherboard system. Every board features clearly labeled solder pads for motor leads, track pickups, speaker connections, lighting outputs, and optional stay-alive or keep-alive components. Instead of soldering wires directly to the decoder, you solder to the Decoder Buddy — then simply plug in your 21-pin decoder. This dramatically reduces installation time, eliminates wiring mistakes, and makes future maintenance as simple as unplugging and re-plugging the decoder.
Perfect for modelers upgrading older locomotives, retrofitting DC models, or installing full lighting packages, Decoder Buddy boards allow you to run headlights, rear lights, ditch lights, beacons, markers, classification lights, and interior illumination — all without running out of solder pads or decoder outputs. Many boards include removable plug-in lighting harnesses, making shell removal and servicing far easier than factory wiring ever allows.
Because Decoder Buddy supports all major 21-pin DCC decoders, it’s the ideal solution for advanced sound installs using ESU LokSound 5, SoundTraxx Tsunami2 21-pin, and other modern decoders. Whether you're performing your first DCC install or you're a seasoned locomotive rebuilder, NixTrainz Decoder Buddys provide the cleanest, most modular, and most future-proof DCC wiring platform available today.
