Raspberry Pi NB-IoT HAT: Built-in SIM7028, supports global frequency bands for NB-IoT communication, compact size, and low power consumption.
SIM7028 NB-IoT HAT is a small, low-power, and powerful Raspberry Pi expansion board with NB-IoT (Narrowband Internet of Things) functionality. It is globally compatible and supports TCP, UDP, LWM2M, COAP, DTLS, DNS, NTP, PING, HTTP(S), MQTT(S), TLS/SSL, and other features. It provides an optimal solution for applications with low latency, low power consumption, and low throughput, making it suitable for IoT applications such as smart metering, remote control, asset tracking, remote monitoring, remote healthcare, and shared bikes.
