Description
The SIM808 module is a comprehensive cellular and GNSS development platform designed for embedded IoT systems requiring reliable 2G connectivity and precise location services. Its integrated architecture merges a SIMCom quad-band GSM/GPRS transceiver with a dedicated GPS receiver, managed via standard AT commands over a UART serial interface. This simplifies firmware development for tracking, telemetry, and emergency communication projects.
Engineered for field deployment, the board supports a wide operational temperature range from -40°C to +85°C and includes dual antenna ports (SMA and IPX) to ensure strong signal acquisition for both cellular and satellite networks. The integrated power management circuitry provides charging control for single-cell Li-Ion batteries, while the high-voltage input port allows direct connection to vehicle or industrial power systems, making it a versatile core for portable and fixed-location applications.
