Customize, inspect, or contribute – we champion open-source hardware innovation. High-Speed CAN & CAN-FD Ready Supports classic CAN 2.0A/B (1Mbps) AND next-gen CAN-FD for faster data streaming. Flash to slcan firmware to unlock CAN-FD capabilities. Multi-Firmware Flexibility & Rugged Design​ Flash compatible firmware (like slcan) for CAN-FD or other needs, enabling seamless integration with diverse CAN tools (PCAN, Kayak, Python). Ruggedly housed for reliable performance during updates and use. Specification Review: Works beautifully - I am using it on an Ubuntu Linux system, and it worked just as well as a Canable with the alternate firmaware. Review: Works with Savvycan on Linux - The first thing that I did when I got this was install the candlelight firmware from the canable website. This went smoothly with no issues. I have successfully used this with SavvyCan running on Linux mint with minimal configuration. Mine came with the screw down connectors for the wires which is not as convenient as the lever type it is shown with but it still works fine. Overall, this is a good option for an all in one can bus reader that is mostly ready to go out of the box. I was able to connect to my car first try after installing the candlelight firmware as mentioned. This does what an esp32 plus a can transceiver like the mcp2562 with the added benefit of can-fd support, which the esp32 cannot do, in one compact package and a very reasonable price for everything this can do. ## Features - DSD TECH: DSD TECH focuses on the development of communication connection devices such as USB/Serial/Wireless.
