The **EPC-R3710IO-XAA160** is an industrial-grade ARM-based Box PC developed by Advantech. It is built around the Rockchip RK3399 SoC and is designed for high-performance IoT edge computing, retail kiosks, and industrial automation. --- ### Core Electronic Specifications | Component | Technical Detail | | :--- | :--- | | **Processor (SoC)** | Rockchip RK3399 (Dual-core Cortex-A72 + Quad-core Cortex-A53) | | **System Memory** | 2GB/4GB LPDDR4 (Model specific, typically 4GB for higher SKUs) | | **Flash Storage** | 16GB eMMC onboard (expandable via MicroSD) | | **Graphics Engine** | Mali-T860MP4 GPU (Supports 4K H.264/H.265 video decoding) | | **Operating System** | Optimized for Linux (Debian/Ubuntu) or Android | --- ### Key Connectivity & I/O Interfaces The "IO" designation in the part number signifies its expanded interface capabilities, making it suitable for peripheral-heavy environments. #### 1. Network & Wireless * **Ethernet:** Dual 10/100/1000 Mbps RJ45 ports for redundant networking or internal/external routing. * **Expansion Slots:** 1x M.2 (Key-E) for Wi-Fi/BT modules and 1x Mini-PCIe for LTE/4G connectivity. #### 2. Display & Multimedia * **HDMI:** Supports dual independent displays (via HDMI 2.0 and DisplayPort over USB-C or LVDS/eDP internal headers). * **Audio:** Line-out and Mic-in headers. #### 3. Data Ports * **USB:** Multiple USB 3.0 and USB 2.0 ports. * **Serial Communications:** Includes RS-232/422/485 ports, crucial for connecting to legacy industrial hardware (PLCs, sensors). * **GPIO:** 8-bit General Purpose Input/Output for direct hardware triggering. --- ### Electrical & Environmental Characteristics * **Power Input:** 12V DC input (locking DC jack). * **Power Consumption:** Typically low (under 15W), allowing for fanless thermal management. * **Operating Temperature:** 0 ~ 60°C (Standard grade). * **Mounting:** Supports Wall mount and VESA mount configurations. --- ### Code Sample: Accessing GPIO via Terminal (Linux) In an industrial setup, you may need to toggle a digital output pin on the EPC-R3710. Below is a generic logic example: ```bash # Export GPIO pin (example pin 157) echo 157 > /sys/class/gpio/export # Set direction to output echo out > /sys/class/gpio/gpio157/direction # Set value to High (1) echo 1 > /sys/class/gpio/gpio157/value ```
