The 7Semi EC200U-CN + STM32 Module combines 4G LTE Cat 1 connectivity, GNSS, and an onboard STM32 microcontroller in a compact solution for IoT and embedded applications. The EC200U-CN provides reliable cellular communication with data rates up to 10 Mbps downlink and 5 Mbps uplink. It supports multiple LTE bands along with optional GSM/GPRS connectivity. Integrated GNSS enables positioning using GPS, BeiDou, Galileo, GLONASS, and QZSS. The onboard STM32 controller provides additional processing and system-control capability. Multiple hardware interfaces make the module easy to integrate with sensors, controllers, and other peripherals.
