SIM808 GPS-GSM-GPRS Module

Description

SIM808 GPS-GSM-GPRS Module The SIM808 is a compact, surface-mount communications module that integrates a GSM/GPRS modem and a GNSS receiver into a single SMT package. It was designed to let product designers add cellular voice/data and satellite positioning without integrating multiple separate chips, saving board area and reducing development time. The unit exposes industry-standard interfaces (UART/USB/GPIO/ADC/PCM and antenna pads) and is controlled with standard AT commands. Onboard firmware supports data protocols and networking stacks so the host can send/receive SMS, voice and packet data (GPRS) while the GNSS engine supplies position data in standard NMEA formats. Emphasizing ease of integration, the SIM808 combines power-management modes and an embedded feature set (AT control model, TCP/IP stack support and accessory interfaces) so it can be embedded into battery-powered trackers, vehicle telematics, and other location-aware devices with minimal external components. Features: Integrated GSM/GPRS modem and GNSS (GPS) receiver in a single SMT module. Quad-band cellular support and GPRS data capability. Controlled via standard AT command set (3GPP + SIMCOM enhancements). Embedded TCP/IP, FTP/HTTP and SSL stacks (for data services). Multiple interfaces: UART, USB, GPIO, ADC, PCM, SIM interface and antenna pads. Low-power design with sleep modes for battery applications. Optional Bluetooth and other firmware-dependent features.
