Evolution technical were commissioned to design and deliver a custom wireless-triggered lighting control system for the KSA Pavilion's opening sequence at Expo 2025 Osaka.


Developed in under a week, the battery-powered solution combined bespoke electronics, DMX control, and redundant triggering to provide a reliable lighting reveal for an international live event.

The Challenge


The opening sequence required a compact lighting control system capable of triggering multiple RGBW lighting zones without relying on existing venue infrastructure. The solution needed to be battery powered, easily transportable, quick to assemble on site, and robust enough for a live international presentation.


With less than a week available before shipment, the system also had to be fully engineered, tested, documented, and packed for export within an exceptionally tight programme.

The Solution


Our Lighting and R&D teams developed a bespoke wireless lighting control platform centered around ESP32-C3 microcontrollers and CueCore2 DMX control. A custom handheld transmitter communicated wirelessly with a receiver connected to the lighting controller through opto-isolated GPIO inputs, allowing pre-programmed lighting sequences to be triggered reliably without line-of-sight restrictions.


The entire system was designed as a modular battery-powered package incorporating power conversion, custom wiring looms, and plug-and-play connectors for rapid deployment. To maximise operational reliability during the live presentation, a secondary hardwired trigger was integrated, providing immediate manual control should wireless operation ever become unavailable.
