This shield is well suited for learning, prototyping, and real world applications where remote communication is required. It integrates multiple communication features into a single board, reducing development time and simplifying hardware design.
Features
- Based on the SIM900 GSM and GPRS module
- Compatible with Arduino and Arduino compatible boards
- Supports SMS MMS GPRS and audio communication
- Communication through UART using standard and enhanced AT commands
- Onboard GPIO PWM and ADC pins from the SIM900 module
- Selectable hardware or software serial communication
- Speaker microphone and headphone support for audio calls
- Status and network indicator LEDs for easy monitoring
Specifications
- Network Type GSM Quad Band 850 900 1800 1900 MHz
- GPRS Multi slot class 10 and 8
- GPRS Mobile station class B
- GSM Compliance Phase 2 and Phase 2 plus
- Transmit Power Class 4 for 850 and 900 MHz
- Transmit Power Class 1 for 1800 and 1900 MHz
- Control Interface AT commands GSM and SIMCOM enhanced commands
- Embedded TCP and UDP stack for internet data transfer
- Short Message Service support for text and data transfer
- Real time clock supported
- Low power consumption approximately 1.5 mA in sleep mode
- Operating temperature range from minus 40 to plus 85 degree Celsius
Applications
- Machine to machine communication systems
- Remote control of electrical and electronic devices
- Wireless sensor networks and remote weather stations
- Vehicle tracking systems when combined with a GPS module

Cautions
- Ensure the SIM card is unlocked before use
- The board is supplied without an insulating enclosure
- Observe ESD precautions especially in dry environments
- Default UART baud rate is 19200 bps with 8 data bits no parity and one stop bit
Power and Interface Notes
- SIM900 board input voltage range is 5 to 26 volts with up to 2 amp current
- Recommended power supply is greater than 9 volts at 2 amp
- Power source can be selected between external supply or Arduino 5 volt line
- Hardware serial uses Arduino pins D0 and D1
- Software serial uses Arduino pins D7 and D8
- External antenna connection supported
- Power key allows manual power on and power off control
Note
- Ensure the SIM card is active and not PIN locked
- Default communication baud rate is 19200 bps
- Video tutorials are recommended for hands on setup and usage
