FAQ:
Q: What is sim900a GSM module?
A: SIM900A GSM Module is the smallest and cheapest module for GPRS/GSM communication. It is common with Arduino and microcontroller in most of embedded application. The module offers GPRS/GSM technology for communication with the uses of a mobile sim.
Q: What is a sim900 mainframe?
A: The SIM900 Mainframe is the platform on which a SIM system is assembled. The mainframe provides power, computer interfaces, clock synchronization, and individual module status. Eight internal module slots accommodate single-width and double-width modules.
Q: How to use sim900’s audio interface?
A: With the help of jumpers you can connect (RX,TX) of the shield to either Software Serial (D8,D7) or Hardware Serial (D1,D0) of the Arduino. The shield comes with two standard 3.5mm jacks. One for stereo earphone and other for mono microphone. It allows you to use SIM900’s audio interface to make and receive voice calls and listen FM radio.
Q: What is the voltage of the sim900?
A: This chart from the datasheet summarizes what you may expect: The operating voltage of SIM900 chip is from 3.4V to 4.4V. To keep supply voltage safe at 4.1V, the shield comes with a high current, high accuracy, low-dropout voltage regulator MIC29302WU from Micrel – capable of handling load currents up to 3A.
