Description :
SIM900 GSM GPRS Wireless Development Board is a powerful quad-band communication module designed for IoT, Arduino, robotics, remote monitoring, and wireless data transmission projects. Supporting GSM frequencies 850/900/1800/1900MHz, it enables reliable SMS, GPRS, MMS, and audio communication worldwide using simple AT commands via UART interface.
The module features an embedded TCP/UDP stack for internet connectivity, real-time clock (RTC), selectable serial port, and low power consumption of just 1.5mA in sleep mode, making it ideal for battery-powered applications. With integrated speaker and headphone support, industrial-grade temperature resistance (-40°C to +85°C), and GSM Phase 2/2+ compliance, the SIM900 module delivers stable and efficient wireless communication for both hobby and industrial projects.
