Lightsaber Soundboards Explained: Proffie vs. CFX vs. Golden Harvest vs. Xenopixel V2/V3 (LGT) & SNV4 (TXQ)

Last updated: 12 Apr 2026

The soul of any high-end lightsaber is its soundboard. This tiny, highly specialized microcomputer dictates everything your saber does: how smoothly it tracks your motion, how bright and complex the blade effects are, and how you interact with it.

In 2026, the market is dominated by four major players, each catering to a different type of collector. Whether you're an open-source coder, a prop purist, or a budget-conscious duelist, choosing the right board is the most critical decision you'll make.

1. Proffieboard V3.9: The Open-Source Gold Standard

Created by Fredrik Hubinette, the Proffieboard is the undisputed king of lightsaber customization. It is 100% open-source, meaning a massive global community of developers constantly writes new code, blade styles, and features for it.

The latest iteration, V3.9, features an 80MHz ARM processor, 160kb of RAM, and 512kb of Flash memory—double that of the previous V2.2 board. This extra memory is crucial because Proffie allows for virtually unlimited, highly complex "blade styles" (such as localized flame effects, rain ripples, or unstable cracked energy).

The Advantage: Infinite customization. If you can dream it, you can code it. It offers the most responsive "Smooth Swing" algorithm on the market and drives a powerful 3-watt audio amplifier.

The Catch: The learning curve is steep. There is no user-friendly desktop app; configuring a Proffieboard requires connecting it to a PC, using the Arduino IDE, and writing (or copy-pasting) C++ style code. It is not for the faint of heart.

2. Crystal Focus X (CFX): The Premium Plug-and-Play

Manufactured by Plecter Labs in Belgium (led by Erv Plecter), the Crystal Focus X (CFX) is the premium closed-source alternative to Proffie. For years, Plecter Labs defined the high-end soundboard market, and the CFX remains a top-tier choice for professional installers.

The CFX is an ARM32-based board featuring a 3.2W digital amplifier that maintains constant power and volume over its runtime. It supports 128x32 OLED screens and features a robust 9-axis (or 6-axis) IMU for incredibly accurate motion tracking.

The Advantage: It offers audio and visual quality that rivals (and some argue exceeds) Proffie, but without the need to code. Configuration is handled via simple text files on the SD card or through the highly intuitive CFX Configurator desktop app. It also features the GraFx system for incredibly detailed accent pixel control.

The Catch: It is a closed ecosystem. You cannot invent entirely new behaviors from scratch; you are limited to the parameters Erv Plecter has programmed into the firmware. It is also generally the most expensive board on the market.

3. Golden Harvest V4 (GHv4): The German Engineering Powerhouse

Developed by Sabertec in Germany, the Golden Harvest series has rapidly evolved from a mid-tier option into a true heavyweight contender. The newly released GHv4 is a complete redesign that brings massive quality-of-life improvements.

The GHv4 is powered by a dual-core processor with a dedicated third co-processor, running a real-time operating system (RTOS). It features 10 independent LED channels (4 high-power, 6 accent) and an advanced audio engine capable of playing five sound files simultaneously.

Connectivity is the game-changer. The GHv4 features an onboard WiFi and Bluetooth antenna. You can transfer files, update firmware, and completely configure the saber wirelessly from your smartphone—no cables or SD card removal required.

The Advantage: The GHv4 bridges the gap between Proffie's power and Xenopixel's ease of use. Wireless everything makes this board incredibly user-friendly for long-term collectors.

The Catch: While highly customizable via its app and SD card text files, its blade effect engine, while excellent, still doesn't quite reach the absolute limitless potential of an open-source Proffie setup.

4. Xenopixel V3: The Budget King

Manufactured in China by LGT, the Xenopixel board is responsible for democratizing the Neopixel lightsaber market. Found in nearly all budget-friendly sabers, the V3 iteration offers an incredible feature set for the price.

The Xenopixel V3 includes a 6-axis sensor for Smooth Swing, Flash on Clash, Blaster Deflect, and Lock Up effects. It comes pre-loaded with dozens of sound fonts and supports adding more via an SD card.

The Advantage: Affordability and simplicity. The V3 board features Bluetooth connectivity via the XenoConfigurator app, allowing users to easily change colors, fonts, and basic settings from their phone. It "just works" right out of the box.

The Catch: It is an entry-level board. The audio amplifier is noticeably weaker and less crisp than the other three boards. The Smooth Swing algorithm, while good, lacks the 1:1 "connected" feel of a Proffie or CFX. Most importantly, you cannot create custom blade styles; you are restricted to the pre-programmed ignition and blade effects.
