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.
