The SIM900 is the first member of a new family of ARM926EJ-S based modules doubling the core performance frequency versus most ARM7 based solutions. At the same time, with advanced and innovative design, SIM900 can reduce sleep mode power consuming up to 40% comparing to current industry average.
Furthermore, the footprint of the module is only 24x24x3mm, fitting into most compact system design. Featuring an industry-standard interface, the SIM900 delivers GSM/GPRS 850/900/1800/1900MHz performance for voice, SMS, Data, and Fax in a small form factor and with low power consumption.
Also available is the SIM900D module. This quad band GSM/GPRS module with a footprint of 33x33x3mm is an upgrade for the SIM300/SIM340D.
