Is it just a display or can it be used to setup my vesc controllers
AFAIK, The display is a 2.8 inch LCD with a Vesc-Express(esp32-c3) connected.
On Trampas website, it says "Fully programmable functions & User interface via LISP scripting"
So, while it may not currently ship with a user interface already programmed to run the motor wizard for example, I know that it already has the code infrastructure(LISP, QML) in place behind the scenes to do so.
If I were a betting man, I'd say within the next year or two there will be a feature complete standard user interface created to run on the vesc display.
And if there is some feature that has not been written for it, the whole darn project is open source, which means we can bend it to our will.
Just take a look at the LISP functions documentation, like seriously, scroll all the way to the bottom of the doc to get an idea of what is possible to control:
