The **EPC-R4680** is an industrial-grade, ultra-slim Box PC developed by Advantech, specifically designed for Edge AI applications. It is built around the **Rockchip RK3568** Cortex-A55 Quad-Core processor. Below is a detailed breakdown of its electronic components and hardware specifications. --- ### 1. Core Processing Unit The heart of the EPC-R4680 is the Rockchip SoC, which balances power efficiency with high-performance computing for IoT gateways. | Component | Specification | | :--- | :--- | | **CPU** | Rockchip RK3568 Quad-core Cortex-A55 (up to 2.0GHz) | | **NPU (AI)** | 1.0 TOPS (Supports INT8/INT16/FP16) | | **GPU** | ARM Mali-G52 EE (Supports OpenGL ES 1.1/2.0/3.2, Vulkan 1.1) | | **Memory** | 2GB / 4GB LPDDR4 (Downboard) | --- ### 2. Connectivity and I/O Interface The electronic design emphasizes high-speed data transfer and industrial communication protocols. * **Networking:** Features dual Gigabit Ethernet ports (RJ45) for redundant network setups or internal/external routing. * **Display:** Supports dual displays through: * 1 x HDMI 2.0 (Up to 4K @ 60Hz) * 1 x LVDS or eDP (Internal header for panel integration) * **Serial Ports:** Includes 2 x RS-232/422/485 ports for legacy industrial equipment connection. * **USB:** 1 x USB 3.0 Type-A and 3 x USB 2.0 Type-A. --- ### 3. Expansion and Storage The internal PCB (Printed Circuit Board) layout provides several expansion slots for wireless modules and storage. | Slot Type | Usage | | :--- | :--- | | **eMMC** | 16GB / 32GB onboard flash storage | | **M.2 Key E** | For Wi-Fi and Bluetooth modules | | **M.2 Key B** | For 4G LTE or SATA SSD storage | | **Micro SD** | External slot for memory expansion | | **SIM Slot** | Nano SIM holder for cellular connectivity | --- ### 4. Power and Environment Designed for harsh environments, the EPC-R4680 uses industrial-grade power management components. * **Power Input:** 12V DC input via a lockable DC jack (to prevent accidental disconnection). * **Power Consumption:** Typically low (approx. 5W - 10W depending on load). * **Operating Temperature:** Supports 0°C to 55°C (standard) or -20°C to 70°C (extended range options). * **Watchdog Timer:** Integrated circuit to reset the system automatically in case of software crashes. --- ### 5. Mechanical Design The electronic parts are encased in a fanless aluminum chassis which acts as a giant heatsink, ensuring silent operation and reducing dust intake. ```yaml # Dimensions & Mounting Width: 156 mm Depth: 112 mm Height: 28 mm Mounting: VESA / Wall Mount / DIN-rail (optional) ```
