What’s New

This batch of CANables was manufactured in the USA, and the design was updated with more robust USB connectors. These CANables have an overall higher fit and finish than previous batches.

If you’re interested in purchasing larger quantities (>20), send me a message so I can produce additional quantities to meet your needs.

What is it?

The CANable is a small open-source USB to CAN adapter. The CANable shows up as a virtual serial port on your computer and acts as a serial-line to CAN interface.

On Linux the CANable works natively with slcand, so you can use all of the standard can-utils command-line utilities and even Wireshark to interact with the bus. Using the alternative candlelight firmware, the CANable enumerates as a native socketcan device with no need for slcan.

On Windows and Mac, the CANable works with cantact-app. This is a simple Java application that shows CAN traffic in real-time and allows you to transmit messages on the bus.

For even more flexibility, the canard library allows you to directly talk to the CAN bus from Python. The library is cross-platform and can connect directly to a CANable’s virtual serial port interface. With only a couple lines of code you can decode traffic on the bus, send messages, and more.
