Works beautifully
I am using it on an Ubuntu Linux system, and it worked just as well as a Canable with the alternate firmaware.

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.

Does not work. No drivers
I purchased this to work with Windows and a Jetson Nano to work with CAN Bus data. for both windows and Nano/Linux the device did not install or there where no drivers. Tried to flash the Candlelight firmware, still was not able to use device.

Looks great, nice packaging., can't get it to work.
Maybe i'm missing something, but I couldn't get it to talk to my computer out of the box, was able to reflash it to newer firmware, but it still won't talk. Sending it back. If you can get it to work mechanically it's beautiful, with great connectors.

It works
Dip switch for termination resistor broke on first use. Other than that, works as advertised.
