embsys GSM Modem Quectel 95

The embsys GSM Modem Quectel M95 is a compact and reliable quad-band GSM/GPRS communication module designed to provide wireless voice, SMS, and data connectivity for embedded systems, IoT devices, industrial automation, and remote monitoring applications. Built around the Quectel M95 GSM/GPRS module, this modem enables microcontrollers, development boards, and industrial controllers to communicate over 2G cellular networks. It supports 850/900/1800/1900 MHz GSM frequency bands, allowing it to operate in most GSM networks worldwide where 2G service is available. The modem communicates with host devices through a UART serial interface using standard AT commands, making it easy to interface with platforms such as Arduino, Raspberry Pi, ESP32, ESP8266, PIC, AVR, STM32, and other microcontrollers.

The embsys GSM Modem Quectel M95 supports SMS messaging, voice calling, GPRS packet data, TCP/IP, UDP, HTTP, FTP, and MQTT communication (depending on firmware and application), making it suitable for IoT and machine-to-machine (M2M) communication. It also supports caller identification, DTMF detection, real-time clock (RTC), SIM card interface, and network status monitoring. The modem typically includes onboard voltage regulation, antenna connector, SIM card holder, status LEDs, and serial communication pins for simple integration into embedded applications.

The modem operates from a suitable DC power supply and requires a valid GSM SIM card with an active mobile network connection. Once powered, it registers with the GSM network and can send or receive SMS messages, make voice calls, or transmit data over the cellular network. Developers can control all modem functions through simple AT commands, allowing easy integration into automation systems and wireless communication projects.
