Description

This model of GSM module is commonly used with Arduino and ESP8266 IoT projects.

Note : You need a step down converter module for supplying sufficient amount of current to make the complete signal transmission, otherwise the module will brownout and reset by itself.

Features

  • SIM900A Modem is built with Dual Band GSM/GPRS based SIM900A modem from SIMCOM.
  • SIM900A works on frequencies 900/ 1800 MHz, it can search these two bands automatically.
  • The baud rate is configurable from 1200-115200 through AT command.
  • GSM/GPRS Modem is having internal TCP/IP stack to enable you to connect with internet via GPRS.
  • SIM900A is an ultra compact and reliable wireless module. This is a complete GSM/GPRS module in a SMT 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.
  • Onboard two set power supply interface VCC5 5V power supply, VCC4 interface, 3.5v-4.5V power supply, optional power on self starting (default) and control start.
  • Onboard SMA (default) and IPXmini antenna interface, SIM900A interface reserved reset.
  • Support 2, mobile phone 3,4G card
  • Low power consumption: 1.0 mA (sleep mode)
  • Serial port circuit: support for 3.3V single chip microcomputer
  • TTL serial port: support 3.3 and 5V single chip microcomputer.
  • Antenna interface circuit (SMA bend female port)
  • SIM card circuit (flip SIM slot)
  • The computer can give early computer debugging USB module power supply, a very large amount of data under the condition of the recommended current more than 1A. Standby dozens of mA data can be set to provide dormancy, dormancy of 10MA low power.
