Down the road, I will be looking at using a pi as that will make it easy to drive a larger display. For now, I am focusing on a small (easier to place on the dash) display.
The most difficult and time consuming part of this project has been reverse engineering the CAN bus on multiple Nissan/Infiniti vehicles (like 370, G37, M56, Q50, etc) This is the only way to know if the gauges will work, or what to change in the code so they do work.

Very familiar with that platform, granted when I was using them they were mostly used for WiFi gpio to control relays and the like, but not much else. Im guessing then you're using i2c for the screen output which wouldn't even require going to a pi as there are plenty of larger i2c screens available and the resolution and refresh rates seem to be adequate. More and more impressed with this project the more I learn about it, thanks for sharing!
