Hardware & PCB design
PCB, enclosure, connectors, antenna and power design are reviewed against the installation and operating requirements.

The TK031 is a 4G and 2G vehicle GPS tracker featuring GPS and BeiDou positioning, real-time tracking, remote fuel and power cut-off, ACC ignition detection and a built-in microphone. It supports mobile app and web-platform monitoring for vehicle security and fleet management.
Final pricing depends on configuration, quantity, taxes and shipping.
Sample availability, quantity and lead time depend on the selected model. Confirm the pilot scope before placing a production order.
The TK031 is a professional wired vehicle GPS tracker designed for real-time location monitoring, vehicle security and fleet management. It combines GPS and BeiDou satellite positioning with 4G LTE and 2G cellular communication to provide reliable tracking across supported network regions.
The device supports remote fuel and power cut-off, ACC ignition detection, historical route playback, geo-fence alerts and audio monitoring through its built-in microphone. Vehicle owners and fleet managers can access the device through an Android app, iOS app or web-based tracking platform.
The TK031 supports both GPS and BeiDou satellite positioning. The dual-satellite system improves positioning availability and provides stable outdoor vehicle tracking.
AGPS helps accelerate initial positioning when cellular data is available. LBS can provide an approximate location when the vehicle is inside a parking garage or another area with weak satellite signals.
The tracker sends the vehicle’s position to the cloud platform through a 4G or 2G mobile network. Authorized users can view the vehicle’s latest location, speed, direction, positioning time, ACC status and online status.
The location reporting interval can be configured according to different vehicle-security, fleet-management and mobile-data requirements.
The tracker can work with a relay to remotely interrupt the vehicle’s fuel or power circuit. This function helps prevent unauthorized vehicle use and supports vehicle recovery in the event of theft.
For safety, a remote cut-off command should only be executed when the vehicle is stationary or travelling at a safe, low speed. The relay must be installed by a qualified automotive electrician.
The ACC wire detects whether the vehicle ignition is switched on or off. Fleet managers can review driving time, parking duration, ignition events and unauthorized vehicle use from the management platform.
ACC detection also helps the platform distinguish between active driving, normal parking and abnormal movement.
The integrated microphone enables authorized audio monitoring for vehicle-security and fleet-management applications. Access should be restricted to approved users.
Customers must comply with local privacy, consent and audio-recording laws before enabling this function.
Users can create virtual boundaries around parking areas, warehouses, cities or approved operating zones. The system can generate an alert when the vehicle enters or exits a configured geo-fence.
The tracker can also support overspeed alerts, vibration alarms, abnormal movement notifications and external power disconnection alerts.
The cloud platform stores vehicle location records for authorized review. Users can replay historical routes and check travel times, stop locations, vehicle speeds and previous alarm events.
This function is useful for logistics verification, fleet scheduling, rental vehicle management and investigation of abnormal journeys.
The TK031 supports Android and iOS mobile applications as well as a web-based vehicle-management platform. Users can monitor individual vehicles or manage an entire commercial fleet from one account.
Platform functions include real-time tracking, vehicle lists, route playback, geo-fence configuration, alarm reports, ACC status and remote-command management.
