CAN Bus is something I have wanted to dive into for almost a year now but for one reason or another always made an excuse. Well I finally sat down and it was way less straightforward than I had expected. This was primarily due to scattered instructions, different board revisions, and missing details. However, after coming out on the other side of it all I am super happy with it. I hope this video answers your questions and helps you along with your CAN Bus journey.
