GPRS-Modul SIM900B

Note: SIM300 module connector should be changed to SIM900 module connector. See the difference as inbelow photos shown. SIM900B and SIM300 SIMCOM presents a compact and reliable wireless module-SIM900B which is compatible with the module-SIM300/340 and SIM340E. This is a complete Quad-band GSM/GPRS module in a B2B type and designed with a very powerful single-chip processor integrating AMR926EJ-S core, allowing you to benefit from small dimensions and cost-effective solutions. Featuring an industry-standard interface, the SIM900B delivers GSM/GPRS 850/900/1800/1900MHz performance for voice, SMS, Data, and Fax in a small form factor and with low power consumption. SIM900B can fit almost all requirements in your M2M applications.
