SIM900A GSM GPRS Module with RS232 Interface and SMA Antenna

Description

SIM900A GSM GPRS Module with RS232 Interface and SMA Antenna

The SIM900A Modem incorporates the SIM900A from SIMCOM, a dual-band GSM-based modem. It operates within the 900MHz frequency range and has the capability to automatically search for these two bands. Additionally, the frequency bands can be configured using AT Commands. The baud rate can be adjusted within the range of 1200-115200 through AT commands as well. This ultra-compact wireless module features an interface that facilitates connections with both PCs and microcontrollers through the RS232 Chip (MAX232).

Designed for M2M applications, the SIM900A Modem is ideal for SMS, voice, and data transfer purposes. Its onboard regulated power supply accommodates a wide range of unregulated power sources. With this modem, you can effortlessly perform tasks such as making audio calls, sending and receiving SMS messages, reading SMS content, and handling incoming calls using simple AT commands. This SMT-type GSM module is a complete solution, incorporating a powerful single chip that enables its compact size. It offers serial and TTL outputs for easy integration and utilization.
