K4 Android Machine Board LVDS and EDP for 1080p FHD decoding support

K4 Smart IoT Motherboard

Overview

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.

Key Advantages

• 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.
