The RK3568-based 1U chassis solution offers high reliability and multi-interface support capabilities in fields such as power and transportation. Key features are as follows:

🔧 I. Core Hardware Configuration

‌Processor Platform‌: Equipped with a Rockchip RK3568 quad-core Cortex-A55 processor (main frequency 1.8GHz-2.0GHz), integrating a Mali-G52 GPU and a lightweight AI NPU (supporting 1TOPS computing power) to meet edge computing requirements 13.
‌Storage Configuration‌: Onboard 8GB LPDDR4X memory + 64GB eMMC storage (expandable to 1TB SSD) 13.

🔌 II. Key Interface Capabilities

‌Network Communication‌
- ‌Electrical Ports‌:
  - Dual Gigabit Ethernet ports (10/100/1000M adaptive)
  - Dual Fast Ethernet ports (10/100M adaptive) 13.
- ‌Optical Port Expansion‌: Extends 4G/5G modules via MINI-PCIE/M.2 interfaces, supporting automatic triple-network switching and eSIM card redundancy design 13.
‌Time Synchronization‌:
- Dedicated IRIG-B code interface, achieving millisecond-level high-precision time synchronization, suitable for scenarios such as relay protection and power fault recorders 12.
‌Serial and Control Interfaces‌:
- Supports 18 serial ports (including 12 independent RS485 + 4 multiplexed RS485/RS232), all with ESD isolation protection 13.
- Dual CAN FD interfaces (1Mbps high-speed communication, with isolation protection) 13.
- 20-channel optocoupler-isolated DI/DO, compatible with digital input acquisition and control 13.

⚙️ III. Industrial Reliability Design

‌Power Solution‌: Dual redundant power supplies (100~240V AC input), adaptable to fluctuating power environments 13.
‌Environmental Adaptability‌:
- Wide temperature operation (-40℃~+85℃)
- Metal casing/IP53 protection rating, suitable for harsh industrial environments 13.
‌Communication Redundancy‌: Supports dual-band WiFi (2.4GHz/5GHz) + Bluetooth 4.2, ensuring reliable data transmission 13.

🏗️ IV. Typical Application Scenarios

‌Power Automation‌: Functions as a communication management unit, connecting to smart meters, FTU/DTU devices for data acquisition and edge computing; combined with B-code time synchronization, it ensures millisecond-level coordination for substation monitoring systems 13.
‌Transportation Control‌: Connects to traffic signal equipment and sensors via multiple network ports and CAN FD interfaces, supporting real-time data interaction and edge analysis 13.

The above solution integrates interface scalability, time synchronization precision, and industrial-grade reliability to meet the deployment requirements of demanding scenarios such as power and transportation.
