Description
Module COMX GSM is a stackable 2G communication module with a built-in SIM800C communication module, operating at GSM/GPRS frequencies of 850/900/1800/1900MHz, enabling low-power transmission of SMS text and data messages. The module features a DC power input, allowing it to be powered by an external power supply of 5 ~ 12V. For user convenience in configuring pins, a DIP switch is used for pin settings. This module is particularly suitable for IoT industries such as remote meter reading, smart wearables, smart parking, and municipal management, where ultra-low power consumption and compact size are core requirements.
Note
Compatibility
When used with the Fire controller, due to PSRAM pin (G16/G17) conflicts, please switch the module base DIP switch pins to TX(G0/G13), RX(G5/G15).
