CANTact Pro - Open Source USB CAN Tool

Linklayer Labs has recently launched an open-source USB CAN tool that lets users debug or hack vehicle components. CAN (Controller Area Network) is a serial communication bus that enables microcontrollers and various components like the dashboard, ABS, air conditioner, and other sensors to communicate with each other without a host computer. Named CANTact Pro, the tool helps in improving the original CANtact hardware by adding an extra CAN bus, support for CAN-FD and single-wire CAN (used in most GM vehicles), high-speed USB, and electrical isolation. The durable case makes it ideal for bench-top and garage environments.

The CANTact Pro works with Windows, MacOS, and Linux with USB drivers, command-line interface, and Python, C/C++, and Rust APIs available for all three operating systems. On Linux, SocketCAN can be used with many existing programs. On Windows, ETAS BUSMASTER is supported. It is the second USB to CAN devices from Linklayer Labs and adds one extra CAN interface, support for CAN FD and SWCAN, as well as USB / CAN isolation compared to the original CANTact device.
