The Kvaser Leaf v3 represents one of the easiest and lowest-cost methods of connecting a computer to a CAN bus network in order to monitor and transmit CAN and CAN FD data. With its standard USB 2.0 connector and 9-pin D-SUB connector, the Leaf v3's sleek, ergonomically designed housing is both robust enough for everyday use and small and flexible enough to be used in space-constrained applications.

The updated Leaf v3 can now handle up to 20,000 messages per second, each time-stamped with a 50-microsecond accuracy. No external power is needed and galvanic isolation is standard. Now with silent mode and CAN FD support.

  • 20,000 messages per second, each time stamped with a resolution of 50 μs.
  • Supports CAN FD, up to 8 Mbit/s.
  • Powered through the standard USB type “A” connector.
  • Quick and easy plug-and-play installation.
  • Supports silent mode for analysis tools – listen to the bus without interfering.
