Description
The SIM808 Bluetooth Compatible GSM/GPRS/GPS Module is a comprehensive development platform centered on the SIM808 system-on-chip, merging global 2G cellular communication, satellite navigation, and short-range wireless connectivity. It operates across all standard GSM frequency bands, enabling SMS, GPRS data transmission, and voice calls, while its integrated MT3337 GPS receiver delivers precise location tracking with cold-start sensitivity as low as -148dBm. The board is engineered for robust IoT system integration, featuring dual antenna ports (SMA and IPEX) for flexible RF deployment and a wide-input voltage regulator supporting direct DC or lithium battery power for field deployments.
Designed for developers and system integrators, the module provides a single UART serial interface with automatic baud rate detection, allowing seamless switching between GSM and GPS functions via AT commands. Its compact form factor, extended operating temperature range (-40°C to 85°C), and included GPS/GSM antennas make it suitable for building asset trackers, remote telemetry units, portable navigation devices, and emergency communication systems using popular platforms like Arduino IDE or Raspberry Pi.
