This GPRS GSM module based on the SIMCom SIM800L, which it a GSM GRPS Quad-Band module. You can add voice, text, SMS, and data to your project with this module. Sim800L is an ideal solution for M2M applications, suitable for automotive, industrial and PDA, personal tracking, electricity environment detection, wireless POS, smart metering, and other M2M applications, to provide comprehensive GSM / GPRS text messaging, voice and data transmission services.
The SIM800L module supports quad-band GSM/GPRS network, available for GPRS and SMS message data remote transmission. The SIM800L communicates with microcontroller via UART port, supports command including 3GPP TS 27.007, 27.005 and SIMCOM enhanced AT Commands. It also has built-in level translation, so it can work with microcontroller of higher voltage than 2.8V default. Besides, the board also supports A-GPS technique which is called mobile positioning and gets position by the mobile network.
