Product description: C-Back NB-loT communication module - SIM7020G - for M5StickC and M5StickC Plus - M5Stack A113
C-Back NB-loT is an NB-IoT communication module adapted to work with M5Stack modules of the M5StickC and M5StickC Plus series. The module is equipped with the SIM7020G chip, which covers most of the global CAT-NB frequency band, has an integrated interface for connecting an external SMA antenna , which improves the quality of communication and stabilizes the signal. C-BACK NB-IoT SIM7020G supports the most popular IoT communication protocols (MQTT, HTTP, CoAP, etc.), which are very often used in applications and scenarios that require low latency and low bandwidth. It can be programmed with Arduino IDE, UIFlow as well as AT commands .
The manufacturer has also prepared a user's guide , in which you will find a diagram of the system and sample program codes - check it out!
