PRODUCT DETAILS

Description

COM GSM is a stackable 2G communication module, with the SIM800C communication module built-in. The working frequency of COM GSM is GSM/GPRS 850/900/1800/1900MHz,and it can transmit SMS and data information with low power consumption. The module has a DC power input and can provide 5V-12V power supply through an external power supply. In order to facilitate the user to configure the pins, the DIP switch is used to set the pins. This module is especially suitable for remote meter reading, smart wearables, smart parking, municipal management and other IoT industries with ultra-low power consumption and small size as the core requirements.

Notice

When used with the FIRE main control, due to the PSRAM pin conflict, please switch the DIP switch pins of the module base to TX(0/13), RX(5/15), and the device can use USB/ External DC is used for power supply.

When used with Core2 series main control, due to the different order of the base pin array, COM.X base pins TX(16), RX(17) correspond to the actual pins TX(14), RX of the Core2 main control (13) The equipment needs to use external DC for power supply.
