https://www.youtube.com/watch?v=Se2KCVyD7CM This guy designed a canbus sheild, https://store.mrdiy.ca/p/esp32-can-bus-shield/ with diagram . seems cheaper to make a big board and solder down transciever unit above. However this does seem really simple. better make sure you get the right Devboard. has a buck converter for putting in your car and has protection.
