The **IAC-R8** is an industrial-grade ARM-based Single Board Computer (SBC) primarily designed for IoT gateways, industrial control systems, and automation. It is built upon the **Rockchip RK3288** SoC, which defines its core electronic capabilities. ### 1. Core Processor and Memory The "heart" of the board consists of high-performance mobile-class architecture adapted for industrial stability. | Component | Specification | Description | | :--- | :--- | :--- | | **SoC** | Rockchip RK3288 | Quad-core Cortex-A17 (up to 1.8GHz). | | **GPU** | Mali-T764 | Supports 4K video decoding and OpenGL ES1.1/2.0/3.0. | | **RAM** | 2GB DDR3 | Standard configuration (expandable in some variants). | | **Flash** | 8GB/16GB eMMC | On-board high-speed storage for OS and firmware. | --- ### 2. Connectivity & Communication Interfaces The electronic layout of the IAC-R8 is optimized for peripheral communication, which is essential for "Internet of Things" (IoT) applications. * **Networking:** * 1x Gigabit Ethernet (RJ45) for high-speed wired data. * Integrated Wi-Fi (2.4GHz/5GHz) and Bluetooth 4.0 module. * Mini-PCIe slot for optional **4G/LTE** cellular modules. * **Serial Communication:** * Multiple UART headers (RS232/RS485 levels) for connecting to PLC (Programmable Logic Controllers) or sensors. * **USB Ports:** * Multiple USB 2.0 Host ports and one USB OTG for firmware updates. --- ### 3. Audio & Video Subsystems The board is capable of driving high-resolution displays, making it suitable for HMI (Human Machine Interface) applications. * **HDMI:** Supports v2.0 for 4K @ 60fps output. * **LVDS/EDP:** Internal headers for direct connection to raw LCD panels. * **MIPI-CSI:** Interface for camera modules. * **Audio:** Integrated Codec with 3.5mm Jack and Speaker headers (usually 8Ω/2W). --- ### 4. Power and Industrial Protection Electronic reliability is managed through a robust power management circuit. * **Input Voltage:** Typically wide-range DC input (12V is standard). * **PMIC:** Dedicated Power Management IC to handle multi-rail voltage regulation (1.8V, 3.3V, 5V) for the CPU and peripherals. * **Watchdog:** Hardware Watchdog Timer (WDT) to automatically reset the system in case of a software hang. --- ### 5. GPIO and Expansion For custom electronics integration, the board features a high-density expansion header: ```markdown - GPIO: General Purpose Input/Output pins for manual logic control. - I2C: For connecting digital sensors (temperature, pressure). - SPI: For high-speed serial data to displays or external chips. - ADC: Analog-to-Digital converter pins for reading analog sensor values. ```
