Do you have any experience with that one? There are a ton of display
boards for BTT controllers but what I haven't been able to find is a
list of what's compatible with which.
This is an iffy question to ask me as I do not use displays. I use
spelling correction.
klipper, moonraker and fluidd running on a bananapi-m5, which has a hdmi
output so the operating monitor can be anything up to a 27" curved HP to
a 13" intended for dual monitor use on the better laptops. I am using
one of the 13" on the ender5. That might need a magnifying glass to read
if as fluidd screen tells you everything. in tiny print.
Stepper drivers shouldn't be a issue since it looks like it takes
normal StepStick / Pololu modules. I see someone did get around to
making the bleedin obvious accessory, the StepStick breakout to screw
terminals.

That would enable driving big motors with high power external drivers.

I'm running into the same problem in 3d printers, Peter. I am currently
rebuilding an Ender5+ using the new stepper/servo drives from hanpose,
that are rated for up to 90 volts for the nema 17 motors used on most
printers. Most of the big tree tech controller boards use 1.5 micro-sec
step pulses, but I am finding I need to stretch that to 2 micro-secs if
I don't want an occasional miss, this while driving the lc42 driver.
These drivers all have opto inputs, and need a little longer step on the
less than 5 volt signals.
