As public legal services continue to become more accessible and digitally connected, self-service kiosks are playing an increasingly important role in delivering convenient legal assistance. Deployed in courts, government service centers, community centers, and industrial parks, these terminals can provide legal information, consultations, document services, and other public services around the clock.
For these applications, the hardware platform must deliver reliable processing performance, rich I/O, flexible connectivity, multimedia support, and long-term stability.
ShiMeta IoT-3399E six-core smart terminal motherboard provides a mature hardware platform for public legal service self-service kiosks, supporting interactive displays, cameras, card readers, printers, network connectivity, and other peripherals in one integrated solution.

A modern public legal service kiosk typically needs to support multiple functions, including:
These requirements make the motherboard a critical component of the overall kiosk architecture.
ShiMeta IoT-3399E is designed for smart terminal applications that require strong multimedia capabilities, extensive peripheral connectivity, and reliable long-term operation.

Powered by the Rockchip RK3399 six-core processor, featuring 2× Cortex-A72 + 4× Cortex-A53 cores with a clock speed of up to 1.8GHz, IoT-3399E provides sufficient processing performance for interactive kiosk applications.
The integrated Mali-T860 GPU supports high-definition graphics rendering and multimedia applications, helping deliver responsive touchscreen operation and smooth visual interfaces.
Public service kiosks may require multiple displays for different functions.
IoT-3399E supports multiple display interfaces, including:
This allows manufacturers to configure a primary touchscreen for service operations while using a secondary display for public information, instructions, or promotional content.
A legal service kiosk may integrate numerous peripherals into a single terminal.
IoT-3399E provides:
These interfaces can connect to:
This extensive connectivity simplifies hardware integration and helps manufacturers build multifunctional self-service terminals.
The MIPI camera interface enables integration with camera modules for applications such as facial recognition and remote video consultation.
Combined with the processing capabilities of the RK3399 platform, the motherboard can support a range of interactive and intelligent service functions within the kiosk.
Reliable connectivity is essential for public legal service terminals that need to access online databases and centralized management platforms.
IoT-3399E supports:
This enables remote content updates, device management, data synchronization, and communication with centralized service platforms.
Public service kiosks are expected to operate for extended periods, often in high-traffic public environments.
IoT-3399E supports 12V power input and provides multiple controllable power outputs for peripherals.
Its 8-layer PCB design helps optimize board layout and thermal management, providing a reliable foundation for continuous kiosk operation.
Different legal service platforms may require customized applications and user interfaces.
IoT-3399E supports Android system customization and API integration, allowing developers to build applications for:
The platform also supports system recovery and remote upgrade functions, helping simplify maintenance after deployment.

A public legal service self-service kiosk based on IoT-3399E can integrate multiple functional modules into one terminal:
User → Touchscreen → Legal Service Application → IoT-3399E → Cloud/Service Platform
At the hardware level, the motherboard connects to cameras, ID readers, printers, audio modules, network interfaces, and other peripherals.
This integrated architecture helps transform a conventional information terminal into a multifunctional digital legal service platform.
By using IoT-3399E as the core computing platform, kiosk manufacturers and system integrators can achieve several benefits:
Self-service terminals can provide legal information and basic services beyond traditional office hours.
High-definition display support, touchscreen interaction, multimedia functions, and responsive processing make services easier to access.
Multiple USB, serial, GPIO, camera, and display interfaces reduce the need for additional expansion hardware.
Ethernet, Wi-Fi, and 4G connectivity enable centralized management, content updates, and system maintenance.
The board’s mature hardware design and protection features provide a stable foundation for continuous public-service deployments.
From public legal service kiosks to government self-service terminals and other interactive smart devices, IoT-3399E combines processing performance, multimedia support, connectivity, and peripheral expansion in a compact embedded platform.
For manufacturers and system integrators developing legal service kiosks, government self-service terminals, or smart public service equipment, IoT-3399E provides a flexible hardware foundation for customized deployments.
