M.2 board with two CAN FD interfaces Due to the board`s compact dimensions of 22mm x 60/80mm x 4,4mm it is possible to add another two CAN FD interfaces (acc. ISO 11898-2) to mainboards and single board computers with M.2 slots. Thus, for this kind of application there is no need for an external interface such as USB. The expansion card has two electrically isolated CAN FD interfaces. Thanks to the complete downward compatibility with CAN the board can easily be operated in classic CAN applications. Each CAN interface may be independently guided outwards by optional adapters with DSUB9 connectors. They have an on-board termination resistor that can be switched on via a jumper. For an external connection there are further variants available on request. The board is based on the esd Advanced CAN Core (esdACC) certified according to ISO 16845:2004. It supports DMA, also known as bus mastering, and it can transfer data autonomously to the host-CPU’s memory. This significantly reduces the CPU load and overall latency of the system. Another feature of the esdACC is the use of MSIs (Message Signaled Interrupts) which makes esd CAN boards also suitable for hyper visor environments. Thanks to its high performance the board is perfectly adapted for real time operating systems. esd electronics offers support for native drivers in various systems. In addition, the CAN-M2/402-2-FD supports a high resolution 64bit time stamp, as do all other boards of the 402 series. Software drivers for Windows and Linux are supplied free of charge.
