HT-HC02 WiFi HaLow station module, built on the ESP32-S3 and MM6108Q chips, requires no SDK and can be directly controlled via AT commands with UART transparent transmission. Its compact size and 1.27mm stamp hole interface enable seamless integration into your PCB design. Operating in the license-free Sub-1GHz frequency band, it supports a transmission distance of 1-2 km and achieves a maximum physical layer over-the-air data rate of 32.5 Mbps. This effectively addresses the limitations of traditional Wi-Fi's short transmission range and the slow data rates of other IoT technologies, making it an ideal solution for high-data-volume IoT application scenarios. Main Features: ESP32-S3FN8 + MM6108IQ. Support AT command control. UART pass-through, no SDK required. Channel bandwidth options of 1/2/4/8 MHz. Support frequency range: 902~928 MHz. Max output power: 21±1dBm. 1.27mm stamp hole design, easy to integrate. 40°C to 85°C maximum operating temperature range.
