Module COMX LTE

SKU:M031-A

Description

Module COMX LTE is a 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.

Note

Compatibility

When used with the Fire main control, due to PSRAM pin (G16/G17) conflicts, please switch the module base DIP switch pins to TX(G0/G13), RX(G5/G15).

Power supply switching

The module base has a DC power input interface. When using this interface to connect to a power supply, please strictly follow the input range (5-12V) to prevent module damage. The internal power DIP switch can adjust the voltage level of the internal terminal VIN to adapt to different modules.

Headphone Jack Compatibility Instructions

When using the 3.5mm headphone jack onboard the Module COMX LTE, a 3.5mm male connector with a length of 17mm is required; otherwise, the microphone will not work properly. For connectors of other lengths, use an adapter, or cut a small part of the headphone jack to ensure the headphone plug is fully inserted into the headphone jack. Alternatively, you can enable the onboard microphone via the DIP switch.
