Cervoz Launches M.2 PCIe CAN FD Expansion Cards for Industrial Communications

M.2 PCIe CAN FD Expansion Cards for Industrial Communications

In industrial communications, common options include RS-232/422/485 and CAN Bus. Compared to traditional serial interfaces, CAN Bus supports multi-node connectivity, provides real-time responsiveness, and integrates error detection. This has made it the standard backbone for AGVs/AMRs, robotics and energy systems such as BMS. However, as data demands continue to grow, classic CAN 2.0, limited to 1 Mbps bandwidth and 8-byte payloads, has become a bottleneck. This is where CAN FD comes in. It retains the proven reliability of CAN while offering higher speed and larger payloads, making it a key step for industrial upgrades.
   

How Cervoz CAN FD Addresses These Challenges

Cervoz introduces two new M.2 PCIe CAN FD expansion cards, MEC-CAN-2F02i (dual-channel) and MEC-CAN-2F14i (quad-channel), engineered to meet these exact needs.
   

• Higher Speed, Seamless Transition
  CAN FD delivers up to 5 Mbps data-phase speed and up to 64-byte payloads, reducing cycle times and bus load. Mixed-mode operation ensures CAN 2.0A/B and CAN FD nodes can coexist, minimizing migration risk.
• Industrial-Grade Reliability
  Each port provides 2.5 kV isolation and 15 kV ESD protection, with an operating range of –40°C to +85 °C. The design complies with ISO 11898-1:2015 and ensures dependable operation in 24/7 environments.
• Flexible Form Factors with Full Integration Support
  The MEC-CAN-2F02i uses M.2 2280 (B+M key) with DB-9 connectors for straightforward installation. The MEC-CAN-2F14i features a 3-in-1 breakaway design, supporting 2242, 2260, and 2280 M.2 form factors, with modular daughter boards ideal for space-constrained or multi-channel deployments. Both ship with brackets and cables for ready-to-use integration. Host connectivity is PCIe x1 Rev. 2.0, with support for Windows 7–11 and Linux SocketCAN, plus an SDK to simplify application development and automated testing.
