SparkFun LTE CAT M1/NB-IoT Shields - SARA-R4

SparkFun LTE CAT M1/NB-IoT Shields - SARA-R4 equips the Arduino or Arduino-compatible microcontroller with access to data networks across the globe. These shields add wireless high-bandwidth cellular functionality to the IoT project by maintaining low power consumption and a small Arduino R3 footprint. The LTE Cat M1/NB-IoT shields include a u-blox SARA-R410M-02B LTE Cat M1/NB-IoT modem. Both Cat M1 (Category M1) and NB-IoT (Narrowband IoT) are Low Power Wide Area Network (LPWAN) technologies that are designed to provide cellular communication to small IoT devices. SparkFunThe LTE Cat M1/NB-IoT shields include a ceramic Molex-1462000001 SMD antenna with a gain of 3.8dBi and an operating frequency range of 1.7GHz to 2.7GHz. These shields are ideally used in devices that require long battery lifetimes, like smart metering, smart lighting, telematics, asset tracking, remote monitoring, alarm panels, smartphones, and connected health.
