CyberWatch — Cyberpunk-Themed T-Watch S3 Firmware
A Cyberpunk 2077–inspired custom firmware for the LILYGO T-Watch S3, featuring a neon app grid with system info, clocks, settings, tools, and a flashlight — all skinned in a dark, futuristic aesthetic.
Overview
CyberWatch is a community-built firmware for the LILYGO T-Watch S3 that reimagines the smartwatch interface through the lens of Cyberpunk 2077. The project replaces the stock firmware with a stylised app launcher featuring a neon grid layout, dark color palette, and deliberately retro-futuristic UI elements rendered with LVGL.
Features
The firmware is organised around a five-column app grid (System Info, Settings, Clocks, Tools, and Games). Current apps include battery info, a configurable main clock, a flashlight, and a calculator. The developer's roadmap includes a Roach Race game, stopwatch, KDE Connect client, notification receiver, music player, and step counter.
Technical Details
CyberWatch is built with PlatformIO and the Arduino framework, using LVGL for all UI rendering. The project supports both the T-Watch S3 and T-Watch S3 Plus hardware variants. A demo animation is available in the repository's docs/ folder, giving a clear picture of the UI in motion on real hardware.
