The GSM-900 GSM/GPRS module is a readily available GSM/GPRS module, which can provide the network connectivity to your project. It can do all the work your mobile phone would do like making a call, receive a call, send a message, connect to the internet using GPRS. You can even connect a microphone and speaker to it and converse on your phone calls. SIM900A GSM Module is a dual-band GSM/GPRS engine that works on frequencies EGSM 900MHz and DCS 1800MHz. SIM900A features GPRS multi-slot class 10/ class 8 (optional) and supports the GPRS coding schemes CS-1, CS-2, CS-3 and CS-4. This module can be used in your IoT based projects and embedded systems. This is used in Automobiles, robotics, servers, etc.
- Standard AT commands
- Item Weight: 4.54 g
- Package Dimensions: 12.1 x 10.6 x 0.2 cm
- Adjustable serial baud-rate from 1200 to 115200 bps
- Single supply voltage: 3.4V – 4.5V
- Power saving mode: Typical power consumption in SLEEP mode is 1.5mA
- Frequency bands: SIM900A Dual-band: EGSM900, DCS1800. The SIM900A can search the two frequency bands automatically. The frequency bands also can be set by AT command.
- GSM class: Small MS
- GPRS connectivity: GPRS multi-slot class 10 (default) , GPRS multi-slot class 8 (option)
- Transmitting power: Class 4 (2W) at EGSM 900, Class 1 (1W) at DCS 1800
- Operating Temperature:- 30ºC to +80ºC
- Storage Temperature:- 5ºC to +90ºC
The module is powered by a 4.0V power supply that can deliver up to 2A of current. Care should be taken as any voltage over 4.5V would damage the module. The communication with this module is done through UART Interface. The data is sent to the module or received from the module through the UART interface. So you can communicate with your controller like Arduino, AVR, Raspberry Pi with just two wires.
