M5Stack COMX.LTE Module (SIM7600G)

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.
