M5Stamp CAT-M Module (SIM7080G)

The M5Stamp CAT-M Module from

M5Stack

is a compact global version of the CatM & NB-IoT dual-mode wireless communication module based on the SIM7080G solution.

The module adopts serial communication, Control Via AT Commands, and supports multiple communication protocols. It is designed for applications that need low latency, low throughput data communication in a variety of radio propagation conditions.

This module is well suited for remote control, remote monitoring, remote medical and other IoT applications.
