Frequently asked questions
Which of the two interfaces should I use?
For new projects, take a closer look at USBtingo. CAN-FD and the logic analyzer function are significant enhancements. Due to the integration into python-can many platforms and connected projects (e.g. cantools, canopen) are available.USBtin has been available for a long time, proven in many projects and is supported by a large number of tools and projects. If neither CAN-FD, the logic recording function nor higher throughput is required, USBtin is suitable.
