As an engineer, he has 12 years of experience in testing and development in the automotive industry. After graduation, his first job was related to automotive on-board network and he started to work with CAN products.<\/p>\n\n\n\n

In this article, he will share his thoughts on CAN bus products and his experience of using Kvaser M.2PCIe 4xCAN products.<\/p>\n<\/div><\/div>\n\n\n\n

Technological change, technological innovation<\/strong><\/p>\n\n\n\n

When Bosch first introduced CAN bus technology more than 40 years ago, I'm afraid I never imagined that it would become an indispensable cornerstone of networks in the industrial world. As a member of the intelligent vehicle industry and a lover of digital products, I have been able to experience and witness the development of these two industries, and I can't help but feel some emotions.<\/p>\n\n\n\n

More than 10 years ago, my camera was a Canon 5DIII, and at that time, a 30MB photo put a lot of pressure on the storage, and the popular storage device at that time was theHighly cost-effective mechanical hard disk.<\/mark><\/strong>After a further increase in data volume, I chose toMechanical hard disk group NAS storage solution.<\/mark><\/strong>In 2022, my camera was upgraded to a Canon Specialized Micro and my photo and video storage needs skyrocketed as I used theLightweight and drop-resistant solid state drives<\/mark><\/strong>as portable storage.Digital storage interfaces have gone from IDE to NVME, becoming smaller and faster.<\/mark><\/strong><\/p>\n\n\n\n

Looking at the CAN bus industry, traditional CAN buses have advanced to CAN FD and are now moving to CAN XL.The USB-based CAN card, an important hardware device for expanding the CAN bus network, seems to be stuck in the same place and has been used until now.<\/mark><\/strong>CAN cards, or Controller Area Network cards, usually have multiple CAN interfaces to support additional CAN bus nodes to meet the needs of various application scenarios.<\/p>\n\n\n

In the case of the Kvaser USBCAN, for example, the use of integrated cables undoubtedly increases the reliability of the device interface.However, there is still room for improvement in the size and stability of the CAN card.<\/mark><\/strong>Especially in the rapid development of the intelligent chemical industry, the requirements for CAN cards in the robotics, medical equipment, security and other high-precision control industries are becoming more and more stringent. In order to meet the high standards of performance, stability and compactness required by these industries, CAN card improvement and innovation are particularly important.<\/p>\n\n\n\n

Meet the needs of industrial intelligence development<\/strong><\/p>\n\n\n\n

With the development of Intelligent Driving, R&D and testing are facing unprecedented challenges, especially the efficient collaboration between different systems, CAN card as an important device in the testing and development process is facing a great challenge. Due to the rapid increase of data volume, it is necessary to haveHigher data rates, more CAN bus channels and a more compact design.<\/mark><\/strong><\/p>\n\n\n\n

As a new host interface solution, the M.2 interface is a potential solution to this problem due to its high-speed transfer rate, compact size, and compatibility with multiple communication protocols (e.g., SATA, PCIe, USB, etc.). However, theM.2 interface inside the controller<\/mark><\/strong>As an internal interface it is not convenient to be used as a hot-swap interface for hard disks, and does not meet the hot-swap requirements of many storage devices.<\/p>\n\n\n\n

So, is there a device that can take full advantage of the M.2 interface?How can I expand the number of CAN interfaces and ensure the stability of the interfaces while saving slot space?<\/mark><\/strong> Kvaser has delivered a satisfactory result - the Kvaser M.2 PCIe 4xCAN. This M.2 interface CAN card in the form of a split interface cleverly expands enough interfaces with minimal space and resources.<\/p>\n\n\n

\u2460 Small and compact design<\/a><\/div>\n<\/div>\n\n\n\n

The dimensions of the M.2 card 22 x 80 mm and a height of only 2 mm make this CAN interface communication card very compact. The four CAN modules are connected to the M.2 card via 30 cm long PCB-PCB cables, which on the one hand enable the distributed connection of the CAN modules to the M.2 card.Closer to the CAN network itself<\/strong>\uff0c<\/mark>thereby maximizing signal speed and integrity; on the other hand, it also makes itsSuitable for all kinds of industrial control chassis.<\/mark><\/strong>Especially in cases with a limited number of card slots.<\/p>\n\n\n\n
