I've never done any hardware hacking or coding (other than the occasional one on my C64 "back in the day" :). I have however worked with Linux as a developer, administrator/operator and architect for the last 30+ years, so I'm not completely useless :).
I'm a bit of a loss to what device I need. All these seem to have at least two CAN bussees
- Teensy 3.6 without headers - https://www.adafruit.com/product/3266
- PJRC Teensy 4.0 USB Development Board - https://www.adafruit.com/product/4323
- PJRC Teensy 4.1 Development Board - https://www.adafruit.com/product/4622
However, looking at the PJRC page for the last two, it say:
Where do I find this "CAN transceiver chip"?3 ports for CAN bus allow connecting to automotive & industrial control systems which use CAN communication. A CAN transceiver chip must be added to complete the electrical interface between Teensy 4.1 and the CAN bus.
I do see a future need for GPS and 3/4/5G, but can I add a module for that?
