The GTR-388NB is a compact, rugged NB‑IoT GPS tracker purpose-built for eBikes, motorcycles, scooters and light vehicles. As a Plaspy compatible device, it delivers waterproof, low‑power real‑time tracking and reliable telemetry in harsh outdoor conditions. Its small form factor and straightforward wiring make installation quick, while the built‑in GNSS and GSM antennas plus AGPS support ensure consistent position fixes for fleet management and anti‑theft workflows.
Designed with vehicle telematics in mind, the GTR‑388NB supports NB‑IoT communication on bands B3, B8, B20 and B28 and transmits data over UDP. With an internal motion (G) sensor, LED status indicators, an 820 mAh rechargeable backup battery and optimized power management, this Plaspy compatible GPS tracker balances long standby life with dependable live updates. Optional accessories (relay, OBDII cable, emergency button, firmware/debug cable) simplify integration into shared micromobility and motorcycle anti‑theft solutions.
Key Highlights
- Plaspy compatible NB‑IoT GPS tracker for reliable real‑time tracking and fleet management of light vehicles and scooters.

- Built‑in high‑sensitivity ceramic patch GNSS antenna and AGPS support for faster fixes and accurate position data.
- Multiple I/O for ignition (ACC) detection, emergency button input, analog telemetry (0–28 V) and relay control for immobilizer or accessories.
- NB‑IoT connectivity on B3, B8, B20, B28 with UDP data transport—suitable for low‑bandwidth, wide‑area deployments.
- Compact, lightweight form factor (107.5 x 38.7 x 22.8 mm, 66.5 g) for unobtrusive mounting and shared mobility fleets.
How It Works with Plaspy
When integrated with Plaspy, the GTR‑388NB streams position and vehicle telemetry to your Plaspy account using NB‑IoT. Plaspy ingests UDP packets from the tracker and converts them into live map markers, geofence events, historical trails and alert notifications. Plaspy’s dashboard and APIs make it easy to combine the GTR‑388NB’s telemetry with other data sources for unified fleet management and anti‑theft workflows.
- Real‑time location and telemetry updates: GNSS coordinates, timestamp, and motion state are forwarded to Plaspy for live tracking and history playback.
- Ignition status and ACC detection: the dedicated ACC input reports ignition on/off events to Plaspy for trip logging and engine state monitoring.
- Analog telemetry (0–28 V): supports voltage‑based sensors—usable for fuel monitoring or battery voltage reporting when configured with Plaspy.
- Remote immobilizer / relay control: the negative‑trigger digital output can be used as an immobilizer control via Plaspy commands when paired with an appropriate relay accessory.
- Emergency and tamper alerts: a dedicated emergency input and internal motion (G) sensor enable theft and movement alerts routed to Plaspy notifications.
- Data consolidation: Plaspy can combine GTR‑388NB telemetry with other sensor data (including Bluetooth sensors managed separately) for richer monitoring and reporting.
