M5Stack COM LTE 4G Module SIM7600G

COM.LTE (4G) is a stackable multifunctional LTE communication module, featuring a built-in LTE communication module SIM7600G. It supports LTE-TDD, LTE-FDD, WCDMA, and GSM frequency bands, with LTE CAT4 capabilities (downlink speed of 150 Mbps). The module supports voice calls and SMS functionality. It offers stable performance, a compact design, and high cost-effectiveness, enabling the transmission of SMS and data information with low power consumption.

The module includes a DC power input and can be powered with an external supply ranging from 5V to 12V. To facilitate user configuration of the pins, a DIP switch is used. The onboard microphone and 3.5mm headphone jack allow for the connection 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 Internet of Things applications.

COM.LTE (4G) RXD/TXD can be connected to M5Stack's UART (TX(0/13/17) RX(5/15/16)) by adjusting the DIP switch. The GPIO in M5Stack Fire 16/17 is connected to PSRAM by default, and it is recommended to use one of the remaining two groups of pins.

When in use, set the DIP switch on the side of the audio configuration pin to ON.
