Описание
Product description: Waveshare NB-IoT HAT - GSM SIM7020E - Raspberry cover plate Pi 4B/3B+/3B/2B/Zero.
NB-IoT overlay for Raspberry Pi, which allows for creating GSM network connections. Supports communication protocols such as LWM2M/COAP/MQTT. Communicates via serial interface UART (RX, TX)via AT commands.
NB-IoT (NarrowBand-Internet of Things) is a communication technology used in IoT. Its main advantages are low power consumption, low cost of devices and good range. Applications in which they are used are: monitoring, tracking, mobile POS terminals, smart metering devices, etc.
