The CBack NB-IoT is an NB-IoT communication module adapted to the M5StickC/C Plus series, with a built-in SIM7020G module that covers most of the world's Cat-NB frequency band. It integrates the SMA external antenna interface, improves the communication quality, and the signal stability of the device. It supports a variety of common IoT communication protocols (MQTT, HTTP, CoAP, etc.), which is suitable for various low-latency and low-throughput application scenarios.
Features
- Compatible with M5StickC/C Plus series
- AT command control, UART transmission rate: 115200bps
- SIM card type: Nano
- External antenna: SMA antenna
