SiteDevAdmin — Fri, 27 Feb 2026 19:07:26 +0000

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.

For customers wishing to use the Kvaser Leaf v3 CB as a direct replacement for the Kvaser Leaf Light HS v2 CB (00733-8), the Kvaser Leaf v3 CB retains the same dimensions and the same mounting hole locations and LED positions. New soldering options cater to requirements for alternative connectors or self-build PC applications.
