CQS291 LTE Cat 4 Android Smart IoT Modules
The CQS291 is a part of Cavli's C-Series module family, featuring LTE Cat 4 modules that support data rates of up to 150 Mbit/s downlink and 50 Mbit/s uplink, with 2G fallback. These Android smart modules are equipped with a Cortex A53 quad-core CPU and a built-in Adreno™ 702 GPU, delivering superior graphics, exceptional image quality, and powerful compute performance. Available in global variants with various memory configurations, the series supports multi-constellation GNSS, including GPS, BDS, GLONASS, Galileo, QZSS, and SBAS. Additional features such as USB 3.1 Type-C/Micro USB, Wi-Fi, Bluetooth, and FM. CQS291 offers an optional integrated eSIM, providing global connectivity through the Cavli Hubble IoT platform for seamless deployments across various applications.
Targeted at two-wheeler automotive applications, the CQS291 utilizes the QWM2290 chipset and integrates Qualcomm's LA2.1 Automotive Middleware for advanced telemetry and device management. It maintains robust LTE Cat 4 connectivity with 2G fallback, along with similar processing power and GNSS capabilities as the CQS290. However, it is specifically tailored to meet the demands of two-wheeler environments, offering enhanced telemetry for automotive use.
