What is a saber core?
A saber core is the electronics package inside the hilt. It’s what makes the blade ignite, what makes the sound play, what makes the light do more than just glow. Everything else in a build — the blade, the emitter, the pommel — hangs off decisions the core enables or forbids.
Five cores appear across the ARTSABERS catalogue. They divide roughly into three tiers: base-lit (RGB-X, S-RGB), smart pixel-compatible (Xenopixel V3, SNV4 PRO), and full-custom enthusiast (Proffie 2.2). The tier a hilt uses is the single biggest determinant of what the hilt costs, what it can do, and how much you’ll fiddle with it once it’s yours.
The rest of this guide walks through each core in order — its story, its specs, its trade-offs, and the archetype of duellist or collector it’s built for. If you want the short answer, the TL;DR above has it. If you want to know why, read on.
RGB-X
The base-lit workhorse. Cheapest way into a proper hilt.
RGB-X is the entry point. A single strip of high-intensity LEDs runs the length of the blade, colour-shifting through the RGB spectrum via a small onboard driver — think of it as a very good torch, cinematically tuned. It exists because someone needed to make a proper-feeling saber that a first-time buyer could actually afford. That mission still defines it.
What it does well: it ignites fast, the blade colour is genuinely vivid, and the Bluetooth module lets you shift hue from your phone without opening the hilt. Fonts are limited (ten to fifteen, mostly the canonical hums and clashes) but they’re decent recordings, not the compressed screech you get on the £80 Amazon sabers. The build tolerances hold up. Nothing rattles.
Where it falls down: no pixel blade support. That means no blaster-deflect flash mapped to a strip position, no crystal-glow pulse, no wipe-in / wipe-out ignition. If you’ve ever seen a Xenopixel next to an RGB-X, the visual gap is genuine — base-lit is base-lit. Duelling holds up to enthusiastic sparring, but the LED strip inside a base-lit blade can’t take the sustained knocks a pixel blade shrugs off. It’s a starter tier for a reason.

Base-lit’s smart cousin. Best light for the price.
S-RGB is what happens when the base-lit tier gets a second draft. Same core idea — single-strip LED, colour-shifting via Bluetooth — but the electronics are a generation newer, the sound chip is doubled in capacity, and the hilt tolerances tightened up meaningfully. Around twenty sound fonts, mixed cleaner. This is where the base-lit tier stops feeling like a compromise and starts feeling like a choice.
What it does well: sound. The step up from RGB-X to S-RGB is more audible than visual — a heftier hum, cleaner clash cracks, transitions that don’t crackle when you swing hard. If you spend your time actually swinging the hilt rather than posing with it lit, this is the difference you’ll feel first. Motion detection is also noticeably better. A wrist-turn ignition works on the first try instead of the third.
Where it falls down: still base-lit. All the RGB-X trade-offs on the blade side apply here too — no pixel effects, no strip-mapped flashes, blade durability is capped at what a light-duelling LED strip can take. Buy an S-RGB if you love the tier for what it is. Don’t buy it hoping it’ll feel like a Xenopixel — it won’t, and that’s not the point.

Our mid-tier pick. Best all-round core we stock.
Xenopixel V3 is where a saber stops feeling like a very good prop and starts feeling like a real thing. Full Neopixel compatibility — every pixel in the blade addressable individually — means you get real ignition wipes, blaster-deflect flashes that hit at the impact point, unstable-blade flicker with actual randomness. Over a hundred sound fonts on an SD card you can swap yourself. Bluetooth app control. This is the modern smart-core baseline, and the V3 refresh sharpened almost everything about it.
What it does well: everything the two base-lit cores don’t. Pixel blades are noticeably brighter (the whole strip lights, not just the base), the wipe animations feel cinematic rather than gimmicky, and font-swapping through the app takes seconds. Duelling durability is genuinely better — pixel blades tolerate contact strikes that would kill a base-lit strip. What experienced duellists reach for, in overwhelming majority, is a Xenopixel V3.
Where it falls down: not much, honestly, which is why it’s our pick. Sound-mixing on hard clash-through-swing overlaps can still stutter briefly — the processor is fast, not surgical. Motion sensitivity is standard rather than tunable. And there’s no config-file customisation — you get what the SD card holds, no more. If those three things are dealbreakers, keep reading to the next two cores. If they aren’t, this is the one.

The premium smart core. Where the fit and finish start to feel serious.
SNV4 PRO is the top-shelf smart core. Same pixel-blade compatibility as the Xenopixel V3, but with a step-change under the hood — faster processor, cleaner sound-mixing, higher-resolution motion sensor, and a curated font library that’s been mastered specifically for the PRO’s sound chain. The build tolerances step up too. Threads seat cleaner. Buttons feel tighter under the thumb. It’s incremental, but the increments are real.
What it does well: refinement. If you’re coming off a Xenopixel V3 and you swing an SNV4 PRO, you’ll feel the difference in the clash mix — overlapping strikes don’t stutter, the swing hum tracks your wrist speed with genuine subtlety, and the motion-triggered blaster-deflect fires with less lag. The font library is smaller than Xenopixel’s hundred-plus but every font is deliberately mixed. Nothing feels like filler.
Where it falls down: the price premium over Xenopixel V3 is real, and it buys refinement rather than new capability. You’re not getting effects the Xenopixel can’t do — you’re getting the same effects rendered noticeably better. Whether that’s worth another eighty to a hundred and twenty pounds is a genuine question, and the honest workshop answer is: for competitive duellists and performers, yes; for weekend fun, probably not.

The tinkerer’s core. Open. Configurable. Uncompromising.
Proffie 2.2 is the outlier. Open-source firmware, community-maintained, editable at the config-file level in a text editor over USB. Every parameter of the saber — blade colours, gesture bindings, motion thresholds, button behaviours, blade effects — is a line you can rewrite. Font capacity is unlimited within the hardware’s memory. The community font libraries are enormous. This is what people mean when they say “custom saber” and mean it.
What it does well: everything, if you’re willing to learn it. Colour palettes you dial to a specific shade. Ignition curves you write yourself. A twist-to-mute gesture you invent from scratch. Nothing else on the market lets you shape the hilt this deeply. And because the community is large and long-running, the online resources for common tweaks are mature — forum threads exist for almost every question you’ll have.
Where it falls down: the learning curve is genuine. Out of the box, a Proffie 2.2 hilt behaves like any other pixel core — ignite, swing, clash, done. The magic is one config file deep, and that file is C++ syntax. If you’ve never edited code, you will hit an initial wall. Once you clear it, the ceiling disappears. But you have to want to clear it. The workshop’s honest advice: don’t buy a Proffie because you might tinker one day. Buy it because you already know you will.
