ED20 Tracker Board, GSM GPRS GNSS BT3.0 IoT
€20.40
Tax included
ED20 IoT Tracker Board based on Mediatek MT2503. Supports GSM/GPRS tracking, precise GNSS positioning, and indoor LBS location. Ideal for tracking projects with flexible power options (USB, VIN, or battery).
The ED20 Tracker Board is a development board based on the Mediatek MT2503 solution, designed for advanced IoT tracking applications. It integrates GSM/GPRS communication capabilities and GNSS (GPS/BeiDou) positioning. The board comes pre-flashed with an AT-command compatible firmware, facilitating easy integration into tracking projects.
This board supports automatic power-up tracking, automatically sending GNSS data (or LBS indoor location) to a server via GPRS. It features fast GNSS acquisition, typically fixing a position within 30-40 seconds near a window, with an advertised accuracy of under 10 meters. For indoor environments, it supports GSM-based LBS positioning with an accuracy of approximately 100 meters.
