Overview sim900 gsm gprs shield for arduino

This sim900 gsm gprs shield for arduino is based on the SIM900 chip from SIMCOM and is compatible with Arduino and its clones, as well as other microcontrollers. Making and receiving phone calls, sending and receiving SMS messages, as well as connecting to the internet via the GPRS network using AT commands, are all possible functions.

It is quad-band capable and can communicate over GSM 850 MHz, GSM 900 MHz, DCS 1800 MHz, and PCS 1900 MHz networks, among other frequencies. It has a power jack as well as a toggle switch that allows it to be powered by an external power supply.

SIM900 shield can be powered by a 5V power supply with a current capacity of 2A, or by a 9V, 1A, or 12V, 1A power supply, respectively. Calls can be made using the microphone and speaker jacks that are built into the device.

An RS232 serial port is located on the back of the shield, along with a slot for a 3V CR1220 battery to power the Real-Time Clock (RTC) (real-time clock). The shield can be mounted on top of the Arduino board after the SIM card and battery have been inserted.

Features of sim900 gsm gprs shield for arduino:

  • Compatibility with Arduino and its clones is guaranteed.
  • GSM network with four bands operating at 850, 900, 1800, and 1900 MHz.
  • Using the GSM network, you can send and receive SMS, MMS, GPRS, and audio.
  • The UART interface is supported.
  • The AT commands are supported.
  • Uploading data to a web server is made possible through the use of an embedded TCP/UDP stack.
  • Support for the RTC.
  • There are jacks for both speakers and headphones.
  • With 12 GPIOs, 2 PWMs, and an ADC, this board has a lot to offer.
