Sim808 GSM/GPRS Module – Compact 4G‑Ready Communication Solution

The SIM808 is a low‑profile, low‑power cellular module that integrates GSM, GPRS, GPS, and Bluetooth transceivers onto a single PCB. Designed for IoT, asset tracking, and M2M applications, it supports quad‑band GSM frequencies (GSM‑850/900/1800/1900 MHz) and 2G GPRS (EGPRS/EGPRS‑TDMA). Built around a 1 GHz ARM Cortex‑M3 microengine, the module offers robust, real‑time data connectivity with minimal space and power requirements.

With a small form factor (22 × 26 × 2.84 mm) and a low supply current (< 237 mA at 3.3 Vidle, < 433 mA during VREG activation), the Sim808 optimally balances performance and battery life. Its integrated GPS/GLONASS receiver delivers sub‑5 m accuracy even in urban canyons, making it ideal for vehicle telemetry and location‑aware dashboards.

• Key Spec 1: Quad‑band GSM/GPRS, 2G networks, HSPA+ (GPRS only), 41 Mbps data throughput (GPRS mode)
• Key Spec 2: Integrated GPS/GLONASS, 10 m accuracy, < 1 kHz sampling, battery‑save PTP mode
• Key Spec 3: Bluetooth 2.1+EDRs, 12 dBm transmit power, 200 mW receiver sensitivity
• Common Use Case: Smart asset tracking – combine GPS data and GPRS transmission over secure MQTT to deliver real‑time location and status to a cloud backend.
