The Piccolo STX is a modular, plug-and-play GPS vehicle tracking device with integrated GPS and cellular antennas, available on 4G CAT-M1/NB-IoT networks worldwide with 2G fallback.
In addition to its many telematics vehicle tracking functionalities, the Piccolo STX IoT acts as an IoT gateway, communicating with our family of IoT tags and uploading IoT data to the server for an all-around connected fleet.
Plug & Play integration into any third-party application via API or TCP/IP integration.
Plug & Play installation on any vehicle type.

A modular fleet GPS vehicle tracking device that is easy to integrate and inexpensive to customize to your needs.
Connect a Wireless Links dashcam for fleet safety and monitoring of extreme driving behavior such as sudden acceleration, sudden lane crossing, sharp turns, and sudden braking.
Monitor up to six different compartments with an accuracy of ±0.5°C. Configure periodic readings, change-based reports, and high/low alarm limits.
The Piccolo STX IoT communicates with our family of IoT tags and uploads the IoT data to the server for an all-around connected fleet.
Two digital inputs, one digital output, and one analog input support event logs such as engine on/off, vibration alarms, and door open/close.
When the vehicle is idle for a predetermined time, the unit can switch to transmit in idle mode—for example, every four hours instead of every minute while moving.
Authorize drivers to start the vehicle with driver identification through Dallas keys or passive RFID keys.
An integrated rechargeable backup battery reports its battery level with every GPS transmission.
Stores and forwards up to 5,000 events, sending them automatically when the unit returns to cellular coverage.
Connect vehicle, telematics, IoT, and ELD data through one rugged fleet device.
Connect to almost any vehicle on the road with a variety of cable options.
The Piccolo STX actively reads and reports engine diagnostics, fuel data, driver behavior, temperature data, and more. It also provides visibility into specialized onboard equipment such as PTO status.
Various IoT BLE tags integrate with the Piccolo STX IoT, allowing it to process and forward IoT data for cold chain, asset tracking, inventory management, school transportation, and campus management applications.
Send ECM data through BLE or dual USB/BLE to a mobile device for ELD compliance, providing the reliability of a fixed-mount onboard computer for a fraction of the price.
With a small footprint and rugged design, the Piccolo STX is tested for vibration, shock, moisture, and extreme temperatures for reliable performance across light vehicles, heavy-duty trucks, industrial machinery, and more.
