The PCAN-M.2 allows the connection of CAN and CAN FD networks via the M.2 interface (PCIe) of modern computer boards. With its small format, the plug-in card is ideal for embedded PCs, single-board computers (SBC), and compact embedded applications. There is a galvanic isolation between the computer and the CAN side up to 300 Volts. The card is available as a single, dual, or four-channel version. The CAN FD standard (CAN with Flexible Data rate) is primarily characterized by higher bandwidth for data transfer. The maximum of 64 data bytes per CAN FD frame (instead of 8 so far) can be transmitted with bit rates up to 12 Mbit/s. CAN FD is downward-compatible to the CAN 2.0 A/B standard, thus CAN FD nodes can be used in existing CAN networks. However, in this case the CAN FD extensions are not applicable.
