Compact embedded board with four distributed CAN modules
Kvaser in Sweden has launched its smallest embedded board with four CAN modules.
The Kvaser M.2 PCIe 4xCAN (01333-9) has four distributed controller area network (CAN) transceivers, adding high speed CAN or CAN FD to any host computer with PCI Express connectivity and an available B or M keyed M.2 slot.
The CAN interface board has a particularly compact footprint of 22 x 80 mm and a height of just 2 mm. The key is that the transceivers are distributed (off-board), allowing them to be located closer to the CAN networks themselves. This layout maximizes signal speed and integrity, making it suitable for higher performance CAN FD systems.
- CAN FD vulnerability threatens vehicle security
- CAN FD group aims at LED networks
- TI introduces integrated CAN FD controller and transceiver
- Microchip adds CAN FD to PIC18 8bit microcontrollers
Each module connects to the M.2 card using 30 cm long PCB-to-PCB cabling. The distributed CAN layout is particularly suited to systems with enclosures. As each channel is individually isolated, optimal galvanic isolation can also be assured. The operating temperature is within the standard industrial range of -40 to 85oC.
The timestamp resolution of just 1 μs and a maximum message rate of 20000 msg/s per channel as well as silent mode, error frame detection and generation allow the board to be integrated in a wide range of embedded systems. Examples range from motor control for mobile robots, automated driving simulation black boxes, to CAN data acquisition in medical automation, fleet management or industrial system monitoring.
“The Kvaser M.2 PCIe 4xCAN board’s small and ultra-slim footprint is a natural progression of our PCI Express range, responding to calls from customers for off-board transceivers,” said Martin Sventén, CEO of Kvaser. “Multiple boards can be combined to provide 8, 12 or more CAN channels within a very small footprint. We see some very exciting use cases for our boards in this format.”
Kvaser’s free-of-charge CANlib SDK can be used to develop software for the Kvaser M.2 PCIe 4xCAN. Programs written in CANlib, which supports Windows and Linux, are fully compatible with present and future Kvaser hardware.
