EDVADO HARDWARE
DOT L4
Compact 2G/4G navigation controller for vehicles and assets, with Bluetooth 4.0 LE and built-in antennas.
61 × 42 × 15 mmCompact enclosure
7–95 VSupply voltage
8BLE sensor slots
IP54Enclosure protection
Built for monitoring
Connected, compact, adaptable
DOT L4 combines positioning, cellular communication and sensor data in a compact navigation controller.
Wireless sensor data
Bluetooth 4.0 LE supports up to eight wireless sensors, including fuel-level and temperature sensors.
Installation flexibility
Built-in GNSS and cellular antennas, a nanoSIM slot and USB Type-C for diagnostics and configuration.
Monitoring continuity
The backup battery supports operation when external power is disconnected; the device reports the switch to backup power.
Capabilities
Made for real-world monitoring
Connect digital, analogue and pulse/frequency sensors. A built-in accelerometer detects motion. The universal BLE integration function supports additional compatible sensors without waiting for a dedicated integration.
Position and transmit
Satellite positioning via GPS, GLONASS, BeiDou, Galileo and QZSS; additional LBS and wireless location-tag methods.
Integrate with your platform
INTERNAL and EGTS protocols with or without authentication are documented. Configuration is available through the Web Configurator, PC Configurator via USB, and SMS commands.
Specification information
Specifications are based on the available manufacturer manuals. Features not described in those documents are not confirmed.
Not specified: absent from sources. Not confirmed: catalog claim without a technical document. Not supported: explicitly excluded by the manufacturer.
