K4 Smart IoT Motherboard
The K4 Smart IoT Motherboard delivers flagship performance for advanced vending machines and smart retail applications, powered by the Rockchip RK3399 hexa-core processor (dual Cortex-A72 @ 1.8GHz + quad Cortex-A53 @ 1.4GHz). This big.LITTLE architecture provides exceptional computing power for AI-driven applications, real-time video analytics, and complex multitasking. The integrated Mali-T860 GPU supports OpenGL ES 3.1 and provides 4K hardware decoding alongside 1080P hardware encoding. What sets the K4 apart is its USB Type-C port, USB 3.0, Gigabit Ethernet, Wi-Fi 5 (802.11 ac) , and LPDDR4 memory — delivering significantly faster data transfer and modern connectivity not found on other K-series boards. Additional features include 6× configurable serial ports (1 TTL, 1 TTL/485, 4 TTL/RS-232), 8× GPIO, HDMI input, multiple display interfaces (LVDS, MIPI-DSI, HDMI 2.0a 4K, eDP), and multi-OS support (Android 7.1/8.1/9.0 and Linux). The K4 is the ultimate platform for premium vending machines requiring AI capabilities, high-speed data handling, and future-proof connectivity.
Hexa-Core big.LITTLE Architecture: The RK3399's dual Cortex-A72 cores handle intensive AI inference and video analytics while quad Cortex-A53 cores manage background tasks — delivering desktop-class performance with excellent power efficiency for demanding vending applications.
USB Type-C + USB 3.0 + Gigabit Ethernet: USB Type-C for modern peripheral connectivity, USB 3.0 for 10× faster data transfer than USB 2.0, and Gigabit Ethernet for high-speed networking — the complete high-speed connectivity suite for data-intensive vending applications.
Wi-Fi 5 (802.11 ac) for Faster Wireless: Built-in 802.11 ac delivers significantly faster wireless speeds than 802.11 b/g/n — enabling quick software updates, real-time inventory syncing, and smooth video streaming for promotional content.
LPDDR4 Memory Architecture: LPDDR4 delivers higher bandwidth and lower power consumption than DDR3 — faster data processing and better energy efficiency for always-on vending machines.
1080P Hardware Encoding + 4K Decoding: 4K decoding for stunning promotional displays, combined with 1080P hardware encoding for efficient video capture — security monitoring and remote diagnostics without CPU overhead.
Multi-OS Flexibility: Supports Android 7.1/8.1/9.0 and Linux (Buildroot/Debian 9/Ubuntu 18.04) — choose the platform that best fits your application and long-term strategy.
The Connectivity King — Type-C, USB 3.0, GbE, Wi-Fi 5: The K4 is the only K-series board with USB Type-C, USB 3.0, Gigabit Ethernet, and Wi-Fi 5 — delivering modern connectivity that future-proofs your vending machines. Faster data transfers, quicker updates, and seamless integration with modern peripherals.
AI-Ready Processing for Smart Vending: The RK3399's Cortex-A72 cores provide the compute headroom needed for on-device AI — run inventory recognition, customer behavior analysis, and predictive maintenance directly on the board. No cloud latency, no external NPU required.
LPDDR4 — Faster and More Efficient: LPDDR4 memory delivers higher bandwidth and lower power consumption than the DDR3 used in other K-series boards — faster response times for customer interactions and better energy efficiency for 24/7 operation.
Future-Proof Connectivity: USB Type-C is becoming the universal standard for peripherals and diagnostics. USB 3.0 delivers 10× faster data transfers for large video files and software updates. Gigabit Ethernet ensures fast cloud communication. The K4 is ready for tomorrow's connectivity demands.
Premium Performance for Premium Vending: For vending machines with high-resolution displays, AI-powered features, and real-time video analytics — the K4 delivers the processing power and modern connectivity that entry-level boards simply can't match. Build the smartest vending machines on the market.
