- BLE 4.2 support for wireless sensors (temperature, door, humidity) and accessory pairing.
- Comprehensive I/O: ignition sense, 2 digital inputs, 3 open-collector outputs, RS232/RS485 and 1‑Wire for telemetry and peripheral control.
- Vehicle-grade power design (9–40 VDC), low-power sleep modes and internal 220 mAh Li‑ion backup battery to maintain reporting during power events.
- OTA firmware updates and support for device management platforms (GEM event manager, GICUS) for scalable maintenance.
How It Works with Plaspy
When paired with Plaspy, the GTU300 streams location and vehicle telemetry over LTE Cat‑1 or GPRS to deliver live tracking, geofence alerts, trip histories and event-driven reports. Plaspy consumes the GTU300’s telemetry—GPS/Wi‑Fi location, accelerometer events, ignition status and serial/1‑Wire sensor data—to power dashboards, alerts and integrations for fleet operations teams. Dual SIM/eSIM and multiple transport options (TCP/UDP/SMS) help maintain connectivity in variable network conditions, while OTA updates keep device firmware aligned with Plaspy features.
- Real-time location and telemetry updates (GNSS + Wi‑Fi fallback)
- Ignition sense and digital input events for trip start/stop and alarm monitoring
- Fuel monitoring and other sensor data via supported fuel sensors and external accessories
- Remote immobilizer capability via external relay integration using the device outputs
- BLE sensors and beacons for temperature, door, and proximity monitoring

Why Choose This Tracker with Plaspy
Choosing the GTU300 for Plaspy deployments delivers a balanced combination of robust connectivity, precise positioning and flexible I/O that telematics teams need. Its LTE Cat‑1 global connectivity with GPRS fallback minimizes data interruptions while dual SIM/eSIM support improves uptime. Multi‑GNSS positioning with Wi‑Fi fallback and strong sensitivity ensures accurate real-time tracking even in urban canyons. The unit’s serial interfaces, 1‑Wire support and BLE 4.2 expand telemetry beyond location — enabling fuel monitoring, temperature sensing and driver/event data to flow into Plaspy for richer analytics.
Operationally, OTA firmware updates and compatibility with established device management platforms reduce maintenance overhead and scale deployments. The GTU300’s wide voltage range, compact form factor and accessory ecosystem (RFID, iButton, relays, fuel sensors, external GPS antennas, SOS buttons) make it straightforward to tailor installations for fleet management, anti‑theft, insurance telematics and rental operations. In short, GTU300 plus Plaspy provides reliable real-time tracking, telemetry and control to help fleets improve utilization, reduce risk and strengthen security.
