'Bare board' version of the popular Kvaser Leaf v3

The Kvaser Leaf v3 CB is the circuit board version of Kvaser's popular single-channel, high speed, USB-to-CAN bus interface, the Kvaser Leaf v3. This board boasts a timestamp precision of 50 µs and support for a wide CAN bit rate range from 20 kbit/s to 1 Mbit/s. The message rate has been boosted significantly to 20,000 msg/s. 

While remaining the industry standard for reliable and low-cost CAN interfaces, the Kvaser Leaf v3 CB introduces an important feature beyond support for CAN FD. Silent mode allows this interface to be used to listen to a CAN bus without transmitting. Find out more about silent mode here.


  • Powered through the USB connector.
  • Supports CAN FD, up to 8 Mbit/s.
  • Quick and easy plug-and-play installation.
  • Supports both 11-bit (CAN 2.0A) and 29-bit (CAN 2.0B active) identifiers.
  • Supports silent mode for analasis tools – listen to the bus without interfering.
  • 20000 msg/s, each timestamped with a resolution of 50 µs.
  • Fully compatible with applications written for other Kvaser CAN hardware with Kvaser CANlib.
  • Support for SocketCAN.
  • Support simultaneous usage of multiple Kvaser interfaces.
  • Compatible with J1939, CANopen, NMEA 2000® and DeviceNet. Higher layer protocol translation handled by the user’s application.
