AWS-Connected LED Strip Controller with nRF9161

Red LED strip controller PCBs with nRF9161 LTE-M module and external antennas

Droid Technologies designed and developed a cloud-connected LED strip controller for remote lighting management, combining cellular IoT connectivity, local wireless control, and AWS cloud integration in a single embedded platform.

The device is built around the Nordic nRF9161 for LTE‑M / NB‑IoT connectivity and an ESP32 as the main controller for LED control, Wi‑Fi, and Bluetooth Low Energy (BLE) communication. The system connects to the AWS cloud using MQTTS and HTTPS protocols, enabling secure remote control, device management, and cloud-based lighting automation.

The controller supports both external and internal antennas, allowing flexible RF configuration depending on installation requirements and enclosure constraints.

Droid Technologies delivered hardware design, PCB development, embedded firmware, AWS cloud integration, wireless connectivity integration, RF and antenna design support, and complete system testing.
