Key Functional Advantages

Versatile LED Display Control

4-line independent management: Each line can display custom content (text, time) separately, meeting multi-information simultaneous transmission needs.
Multi-language universal: Supports over 100 global languages, adapting to cross-regional and multi-ethnic application scenarios without additional font configuration.
Flexible interface adaptation: Directly connects HUB75/HUB08 LED modules; expandable to 4 HUB12 interfaces via expansion boards, compatible with most mainstream LED display specifications.

Interactive QR Code Display

Dual-mode adaptation: Full-screen QR code for long-distance scanning (e.g., parking payment), 3-line QR code with 4th-line text description for short-distance interaction (e.g., scenic spot guides).
Customizable content: QR code supports URL, text, and other content types; excess characters are automatically truncated to ensure normal recognition.
Seamless mode switching: Exits QR code mode with one-click command, restoring original display content without manual reconfiguration.

Multi-Protocol Communication & Expansion

Rich communication ports: Ethernet for LAN long-distance connection, RS485/RS232 for industrial on-site communication, TTL for short-distance device linkage, covering most communication needs.
IoT-friendly protocols: Supports MQTT protocol, enabling easy integration into cloud management systems and IoT platforms.
Access control integration: Wiegand interface directly connects card readers or biometric devices, facilitating access control + display system integration.

Peripheral Linkage & Voice Broadcast

Powerful relay control: 2 high-load relays can link barriers, lights, equipment power supplies, and other devices to realize automatic linkage.
IO status monitoring: Reads sensor, button, or switch signals, triggering preset actions (e.g., equipment alarm, voice broadcast) based on external events.
Flexible voice playback: Stores up to 256 voice files, supports sequential/immediate play modes, suitable for welcome messages, safety alerts, and operation confirmations.

Easy Use & Stable Performance

Low threshold operation: All functions are controlled via standardized protocol commands, no complex programming required, reducing operation and maintenance costs.
Data security & stability: Default parameters are stored in flash memory (not lost after power failure); regular "heartbeat commands" avoid automatic refresh of display content.
Wide environment adaptation: Works in -40°C to +85°C extreme temperatures, with ESD and pulse protection for communication ports, suitable for harsh industrial or outdoor environments.

Application Scenarios

Smart Parking Systems: Display real-time parking availability, pricing, and full-screen payment QR codes; link relays to control barriers and play "payment successful" voice prompts.
Commercial Complexes & Malls: Use 4-line display for floor navigation, brand promotions, and real-time time; display interactive QR codes for coupons, with voice broadcasts guiding consumers.
Industrial Workshops: Display production data, safety guidelines, and equipment status; link IO inputs to detect equipment abnormalities, trigger voice alarms, and cut off power via relays.
Scenic Areas & Public Spaces: Show multi-language safety notices, tour routes, and 3-line QR codes for detailed guides; play welcome voices after visitors scan codes to register.
Access Control & Smart Buildings: Integrate with card readers via Wiegand interface; display visitor information and play "welcome" voices while controlling door access via relays.
Transportation Hubs & Government Facilities: Provide multi-language schedules, directional guidance, and public service announcements; support remote content updates and system upgrades.
