From the ultra-compact M.2 2230, highly compatible Mini PCIe, to industrial-standard PCIe — the entire lineup is powered by our proprietary SUNCAN controller chip. With a bridge-free native PCIe design that completely eliminates conversion latency, pushing the connectivity limits of embedded and industrial control systems.
Supports Key-A+E / B+M slots with high-density quad-channel output. Specifically designed for space-constrained fanless embedded systems and Autonomous Mobile Robots (AMR).
The SUNIX M.2 series features snap-off or ultra-compact designs that flexibly integrate into various custom embedded enclosures and confined spaces.
Designed for the latest generation of slim fanless embedded hosts, ARM-based control boards, and Nvidia Jetson platforms. With 2230/2280 ultra-small form factors, the entire series is MIL-STD certified for shock and drop resistance, making them ideal as the core communication module for AMR/AGV autonomous vehicles and EV in-vehicle systems.
Designed for existing industrial single-board computers (SBC) and standard IPC platforms. Provides perfect backward compatibility, enabling seamless upgrade of legacy production line communication systems to high-bandwidth CAN FD architecture, with SUNCAN controller chip guaranteed supply for 10+ years.
Developed for standard Industrial PCs (IPC). Includes standard and low-profile brackets, with up to 4 fully independent isolated CAN channels per card — the top choice for large battery pack (BMS) test benches and multi-axis robotic arm synchronous control.
Free from external conversion chips, data transfers directly through the PCIe bus, delivering uncompromising stability and protection for industrial automation and EV systems.
Data flows directly through the PCIe bus to the SUNCAN controller chip, eliminating common intermediate bridge chips like USB or SPI, removing additional conversion latency and transmission bottlenecks.
Dynamically control and toggle the 120-ohm termination resistor via API, completely eliminating the hassle of adjusting physical DIP switches or jumpers.
Proprietary APIs and drivers fully support Windows and Linux. Multi-language SDKs (C/C++, C#, Python) and standard SocketCAN support reduce your development integration cycle by up to 50%.
The entire series features built-in 2.5KV signal galvanic isolation, 2KV surge protection, and +/-15KV ESD protection, supporting stable long-term operation across -40 deg C to 85 deg C wide temperature range.
Traditional PCIe-to-CAN cards often use external bridge chip designs, which are prone to latency and transmission bottlenecks under heavy throughput. SUNIX's native PCIe architecture demonstrates uncompromising performance in throughput, transmission efficiency, and response latency.
Direct PCIe bus access eliminates USB or SPI intermediate connections, reaching the physical transmission ceiling with over 1.3x data throughput improvement.
Limited by external SPI bus bandwidth bottleneck, prone to buffer overflow under heavy traffic.
Communicates through MCU-to-USB conversion with significant packaging overhead, noticeably increasing latency under heavy traffic.
SUNIX provides the industry's most comprehensive driver support for Linux and Windows platforms. On Linux, full SocketCAN compatibility enables seamless integration with ROS and AMR autonomous vehicle development. On Windows, our unified core software architecture allows a single function to control both CAN 2.0 and CAN FD devices simultaneously.
CAN 8-Byte and CAN FD 64-Byte share the same read/write functions.
Complete sample source code for C/C++, C#, and Python.
Supports C/C++ - C# - Python - ROS 1/2 - LabVIEW
Auto-detects hardware slots and transmission rates. A single API function supports both CAN (8-Byte) and CAN FD (64-Byte), eliminating the complexity of maintaining multiple codebases.
Native SocketCAN integration, seamlessly compatible with open-source robotics systems.
Unified DLL library package with streamlined interfaces to reduce system development overhead.
CAN 2.0 and CAN FD Modules
SUNIX's complete native CAN FD solution lineup is designed for vertical control environments demanding extreme noise immunity and microsecond-level response times.
Swapping stations must simultaneously coordinate high-frequency charging schedules and real-time health status (SoH/SoC) monitoring for dozens of high-voltage lithium battery packs. SUNIX's native PCIe isolated expansion cards provide up to 2,500 VDC signal galvanic isolation, seamlessly integrating the host IPC with each slot's BMS, charging control units, high-voltage relays, and safety alarm systems, effectively suppressing surge currents generated during high-power charge/discharge cycles.
Select the right card for your smart embedded product or industrial server based on host space & channel requirements.
