LUXERA ONE

Normal glasses. Nothing normal inside.

Standalone AR smart glasses in a thick-acetate frame — a monocular green MicroLED HUD, an always-available camera, a depth sensor, bone-conduction audio, and an on-device Arabic-first assistant. No phone tether. No visor. Just glasses that happen to contain a computer.

✦ What is this?

Luxera One is a from-scratch attempt to build what the big labs keep teasing: AR glasses that look like actual glasses. Everything — compute, batteries, optics, sensors, audio — seals inside a chunky acetate frame. Nothing clips on. Nothing sits in front of the lens.

This repository is the hardware design: KiCad schematics, PCB layouts, and the component library for every board in the device, built in public, one verified pin at a time.

Two physical generations of the same circuit:

✦ Current state

• Product brief, hardware design guide, master build guide (36 pp)
• Component selection — every part verified in stock at JLCPCB/LCSC
• Core bench schematic — FROZEN v0.1 (power chain, RK3566 socket, USB, console, audio, touch, camera/display lanes, inter-board FFC)
• Core PCB layout (4-layer, 55×45 mm) ← you are here
• Aux + Front schematics & layouts
• Fab + assembly via JLCPCB · bring-up · LuxeraOS boot
• Rev-B: bare-SoC in-frame boards (professionally reviewed)

✦ Selected silicon

✦ Repository layout

├── core/      Core board — brain, power, display, audio   (schematic frozen)
├── aux/       Aux board — always-on island, radio          (pending)
├── front/     Front flex — perception                      (pending)
└── lib/       Shared KiCad library (symbols · footprints · 3D)

Open it: KiCad ≥ 9.0 → open core/core.kicad_pro. The lib/ library ships in-repo, so everything resolves out of the box. Parts were imported with easyeda2kicad straight from LCSC IDs.

✦ The story

Designed and built by Mohamad Nihad Alsufe — 16, Syrian, based in Sharjah 🇦🇪 — as part of Hack Club Stardance. Schematic drawn from a blank KiCad install to frozen in a single day of pin-by-pin, datasheet-verified work. Follow the devlogs on the Stardance project page.

⚠️ Honest notes: this is a live work-in-progress, not a kit — build at your own risk. Li-ion cells demand respect. The low-vision assist is marketed strictly as an aid and never as a replacement for a cane, guide dog, or certified mobility device.
