LIGHT CUSTOMIZATION

Tailored Hardware Shipments

We modify standard boards directly at our Shenzhen facility. Avoid manual rework with production-ready components tailored to your enclosure requirements.

Custom Firmware Flashing

Pin Header Modifications

We flash your proprietary firmware onto ESP32 or Arduino boards during final testing, ensuring secure, ready-to-deploy hardware out of the box.

Select straight, right-angle, or female headers. We solder custom layouts with component-level verification before exporting from Shenzhen.
