The Teltonika M2 module weighs under 10g and measures 33.5mm x 38.8mm. With total height only 5.6mm including the SIM holder, the unit allows unobtrusive end products with small overall dimensions. Several features enable easy integration with the host system, including 3.5-4.2V supply range and industry-standard interfaces such as I2C and SPI, two serial ports, and two analogue inputs to an on-board ADC. A 60-pin board-to-board connector and 50Ω RF connector are also provided. The on-board SIM holder supports 1.8V and 3.3V cards.
Embedded software for the Teltonika M2 includes GSM/GPRS protocol stack release 99, SIM Application Toolkit release 99, and an integrated TCP/IP stack aiding integration with web-based applications.
The module is featured for data communication applications such as vehicle telematics for safety and security, automatic meter reading (AMR), security and surveillance systems, remote control and real-time data transmission. GPRS operation is multi-slot class 10, and Circuit Switched Data (CSD) at up to 9.6kbit/s is also supported. The module operates in 850MHz, 900MHz, 1800MHz or 1900MHz bands, with 2W transmit power meeting class 4 requirements for EGSM in 850-900MHz bands. 1W transmit power in 1800/1900MHz bands meets class 1 output power requirements.
