Great value USB to Canbus controller and sniffer
Used in an automation environment to help debug and diagnose logic controllers. Used once so far, great to keep in tool kit for future use. Price good against what the device achieves. Very happy.

Worked perfectly, easy to setup
Simply plug and play installation. Works well with free windows software. Easy to connect with screw terminals. Looks nice with the clear case. No buffer overflows or "filters" to configure to use, a simple stream of CAN data from the bus instead.

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.

Ottimo convertitore
Ho preso questo adattatore da USB a CAN per un progetto che sto preparando da collegare alla mia auto, ed è stata una scelta eccellente. Il dispositivo si è rivelato subito pratico ed efficace, con una configurazione molto semplice e intuitiva. È compatibile con diverse piattaforme, e ho potuto utilizzarlo senza problemi sia su Windows che su Linux, con un’ottima integrazione nel mio ambiente di lavoro. La qualità costruttiva è sorprendentemente buona per un prodotto di questa fascia di prezzo. Il corpo è robusto, compatto e abbastanza resistente per un utilizzo frequente. Durante l’uso, la connessione è stabile e affidabile, e il dispositivo è riuscito a gestire flussi di dati senza interruzioni o perdite. Anche l’aggiornamento del firmware è stato semplice, nella parte posteriore sono presenti due interruttori in miniatura, uno per attivare la resistenza da 120 ohm per il terminatore, e l’altro per avviarlo in modalità boot e scaricare quindi il firmware aggiornato. Finora si è rivelato un ottimo aiuto, e non posso che consigliarlo.

Great adapter, high quality
A great USB to CAN adapter for anyone needing one. It's high quality and will definitely last if taken relatively good care of.
