M5Stack COM.GSM - 2G Communication Module (SIM800C)
€23.90
Tax included
M5Stack stackable 2G communication module with built-in SIM800C chipset. Supports GSM/GPRS 850/900/1800/1900 MHz bands for SMS and data transmission.
DC power input (5V-12V) via external supply. Pin configuration facilitated by a DIP switch. Suitable for IoT applications requiring low power consumption.
Important Notes
When used with the FIRE main control, due to a PSRAM pin conflict, please switch the DIP switch pins of the module base to TX(0/13) and RX(5/15). The device must be powered via USB or an external DC power supply.
When used with Core2 series main controls, due to the different order of the base pin array, the COM.X base pins TX(16) and RX(17) correspond to the actual pins TX(14) and TX(13) of the Core2 main control. The device must be powered by an external DC power supply.
Note: When using a CORE2 or CORE2-FOR-AWS main control to drive this module, please use the DC power input of the main control.
