DFRobot SIM7000C Arduino Expansion Shield

DFRobot SIM7000C Arduino Expansion Shield is a wireless communication module based on the SIMCom SIM7000C. The SIM7000C expansion shield features Narrow Band-Internet of Things (NB-IoT) communication technology. This technology of SIM7000C shield supports cellular data network connection of low power consumption device in Wide Area Network (WAN). The SIM7000C expansion shield supports both SIM card and NB-IoT card and achieves phone calls, messages, and data transmission synchronously. This expansion shield provides a BME280 environmental sensor for measuring temperature, humidity, and pressure. The SIM7000C shield is suited for IoT applications like long-distance control, movement tracking, long-distance data uploading, and shared bikes.
