"CANTact Pro comes with many of the same features as Intrepid Control Systems (ICS) ValueCAN 4.2 CAN tool, but only at a fraction of the cost."

CANtact Pro is part of the Microchip Get Launched design program!

CANtact Pro is an open-source USB to Controller Area Network (CAN) device. This allows you to connect a computer to anything that talks CAN. CAN is used in a wide range of embedded systems including vehicles, robots, industrial control systems, and avionics.

The CANtact Pro improves on the original CANtact hardware by adding an extra CAN bus, support for CAN-FD and single-wire CAN, high speed USB, and electrical isolation.

The CANtact Pro also introduces new software that supports Windows, macOS, and Linux. On all platforms, a command line interface is available for basic interaction with CAN buses. The cross-platform driver support allows developers to build CAN tools that run on all platforms. On Linux, users can take advantage of SocketCAN to use the device with many existing programs. On Windows, ETAS BUSMASTER is supported.
