The Digitax SDK provides a complete, ready-to-use development environment for Android™ applications.
It simplifies the integration of complex automotive interfaces — such as CAN Bus, serial communication, and digital I/O — with Android-based systems, ensuring smooth and reliable data exchange.
Designed for developers and system integrators, the SDK includes:
Comprehensive APIs and libraries for hardware-level access
Sample code and testing tools for faster integration
Support for Android Studio and ADB environments
CAN Bus and RS232/RS485 communication management
Full technical assistance from the Digitax engineering team
With the Digitax SDK, developers can quickly create, customize, and deploy Android applications tailored to fleet management, diagnostics, and connected mobility operations.
Two versions available
mart Box comes in two versions — Base and Pro — each designed to adapt to different professional needs.
• Smart Box Base
Acts as a central communication hub, managing the vehicle’s connectivity.
It collects and transmits data from sensors, CAN Bus, and other onboard systems to your Android smartphone or tablet via a simple USB-C connection.
The app on the paired device then processes, displays, and sends this information to your fleet server in real time.
• Smart Box Pro
Goes beyond data transfer — it includes a built-in Android module that lets you run your own applications directly on the device.
The smartphone or tablet becomes a control and monitoring terminal, while Smart Box handles GPS tracking, Wi-Fi, Bluetooth, and 4G LTE connectivity.
Both versions are fully compatible with the Digitax SDK, giving developers complete freedom to integrate, customize, and scale advanced automotive and telematics solutions.
Designed for professional automotive applications
Smart Box is engineered for professional and commercial vehicles that require constant control, data access, and remote management.
It serves both as an interface module and as a black box, providing full visibility over vehicle status, driver activity, and onboard systems.
Ideal for:
Public transport and fleet vehicles (buses, taxis, service fleets)
Heavy-duty and logistics vehicles (trucks, garbage collection)
Special vehicles (school buses, ambulances, emergency units)
Whether used for fleet tracking, maintenance monitoring, or safety management, Smart Box ensures real-time data collection and reliable communication between the vehicle and the control center.
*Pro Version supports integration with the Digitax Device Track platform for full fleet supervision
Direct connectivity with the vehicle
Smart Box connects directly to the vehicle’s control unit and onboard peripherals, enabling precise, real-time monitoring of system status and performance.
This direct integration allows immediate access to key vehicle data — from speed and engine status to diagnostics and telematics information.
When needed, Smart Box can also communicate via CAN Bus, supporting multiple automotive protocols, including:
FMS (Fleet Management System)
J1939
OBDII
ISO-11992
This flexibility makes it compatible with a wide range of vehicles and ensures seamless communication between the Smart Box, the vehicle’s ECU, and your Android applications.
Available in two versions: BASE and PRO
Smart Box is available in the BASE version and in the PRO version with Android module and GPS, WIFI, 4G LTE and Bluetooth.
Lightweight and compact
Smart Box it’s perfect for unobtrusive installations inside your vehicle
