To meet the growing demand for long-range, high-speed, and stable wireless communication in Internet of Things (IoT) applications, we proudly introduce the HC-02 Wi-Fi HaLow Transparent Transmission Module.
Powered by the advanced ESP32-S3 and MM6108Q chipsets, this module offers exceptional processing capability and can be directly controlled via UART AT commands—no SDK development required.
In Chengdu, November 2025 —The four-day 11th IEEE World Forum on Internet of Things (IEEE WF-IoT 2025), held October 27–30 in Chengdu, SiChuan Province, concluded successfully.

As a Chengdu-headquartered provider of IoT devices and integrated solutions, Heltec participated actively in the forum and returned with important insights across three dimensions: trend capture, field validation and channel engagement.
