The M5Stack COMX LTE Module adds high-speed 4G LTE connectivity to M5Stack projects, supporting data transfer, voice calls, and SMS for applications such as industrial IoT, remote monitoring, and wireless communication systems.

Module COMX LTE is an M5Stack stackable multifunctional LTE communication module, built-in LTE module SIM7600G, supporting LTE-TDD/LTE-FDD/WCDMA and GSM frequency bands, supporting LTE.CAT4 (downlink speed of 150Mbps), and supporting voice calls and SMS.

It has stable performance, compact appearance, and high cost performance, enabling low-power transmission of SMS and data information. The module comes with a DC power input, which can be powered by an external power supply of 5 ~ 12V.

For user convenience in configuring pins, a DIP switch is used to set the pins. The onboard microphone and 3.5mm headphone jack support the insertion of headphones with a microphone. This module is particularly suitable for scenarios requiring high-speed network connections, such as video calls, drone data transmission, and industrial IoT.
