CBack NB-IoT CN

SKU:A112

Description

CBack NB-IoT CN is an NB-IoT communication module adapted to the M5StickC/C Plus series, with a built-in SIM7020C module, covering most of the Cat-NB frequency bands, and integrating an SMA external antenna interface to improve the communication quality and signal of the device The stability. Support a variety of commonly used IoT communication protocols (MQTT, HTTP, CoAP, etc.), suitable for various low-latency, low-throughput application scenarios.

This product is EOL now.
