Check it is type with 26-pin underside connector that directly plugs on top of RPi. It is same dimensions (approx) as the RPi.
It occupies the GPIO plug, making other experimental use of the GPIO pins quite awkward.
It can be made to be the Rpi’s primary GUI screen, including touch stylus “mouse” function.
It is cramped but just workable. You can now avoid use of that HDMI screen!
You WILL still need a real keyboard, and you SHOULD still use a real mouse.
This “recipe” below works ONLY with BS4 operating software. BS3 and earlier? – sorry.
