SIM900A GSM GPRS Module with RS232 Interface and SMA Antenna
SIM900A GSM GPRS Module with RS232 Interface and SMA Antenna
SIM900A Modem is built with Dual Band GSM-based SIM900A modem from SIMCOM. It works on frequencies 900MHz. SIM900A can search these two bands automatically. The frequency bands can also be set by AT Commands. The baud rate is configurable from 1200-115200 through AT command. SIM900A is an ultra-compact and wireless module. The Modem is coming interface, which allows you to connect PC as well as a microcontroller with RS232 Chip(MAX232). It is suitable for SMS, Voice as well as DATA transfer applications in the M2M interface. The onboard Regulated Power supply allows you to connect a wide range of unregulated power supplies. Using this modem, you can make audio calls, SMS, Read SMS, attend the incoming calls and etc. through simple AT commands. This is a complete GSM module in an SMT type and made with a very powerful single-chip, allowing you to benefit from small dimensions. SIM 900A GSM Modem with serial and TTL outputs.

1. What is SIM900A GSM module?
- SIM900A is a small and dependable wireless module. This is an SMT GSM/GPRS module with a very powerful single-chip processor integrating the AMR926EJ-S core, allowing you to benefit from small dimensions and cost-effective solutions.
2. What is GSM and GPRS used for?
- The GSM network is circuit-switched. The GPRS network is packet-switched. GSM technology offers a data rate of approximately 9.6 kbps (kilobytes per second) to all of its users. For all users, the GPRS technology provides a data rate ranging from 14.4 kbps to 115.2 (kilobytes per second).
3. What is the purpose of GSM module?
- A customized Global System for Mobile Communication (GSM) module is designed for wireless radiation monitoring via Short Messaging Service (SMS). This module can receive serial data from radiation monitoring devices such as survey meters or area monitors and send it as text SMS to a host server.
4. Can I connect the SIM900A to the Internet?
- SIM900A supports General Packet Radio Service (GPRS) for internet access via HTTP. This is a complete GSM module in SMT form, made with a very powerful single-chip that allows for small dimensions.
