is it possible to retrofit a 4.3 inch screen to a nanovna that has a 2.3 inch one,has anyone tried this?.

Connections with LCD incompatible, firmware has insufficient free space
See wiki /files for a possible retrofit

from what i can tell a 3.2" will fit,would one of these do the job?,ones resistive and one capacitive on the touchscreen

or:
I dont have mine yet but planing on making a metal case with a bigger screen for it. 73 m3vuv

Another way to do this would be to package it up with an Android tablet and use NanoVNA WebApp as the user interface (remove or hide the built-in LCD).
I'd like to try this but the android app won't load on my older tablet, despite it having been updated to Android 6.1.

It would also be possible to build in a raspberry pi and use nanovna-saver, but the android app seems a better fit if you don't have a keyboard.

Using cho45's NanoVNA apk avoids Internet dependency:


.. and Amazon Fire tablet is currently < US$30

Actually, his Android app still calls home to mama Google for statistics.??

If you have your Android device's WiFi enabled and connected, the NanoVNA app starts right up.
However, I run a firewall (No-root firewall by Greyshirts) on my Android devices and the network request from the NanoVNA app (when it starts up only) takes about 60 seconds to timeout before the main screen appears. If I allow the app through the firewall, it starts immediately.
I spoke to CHO45 about this and he said it's the Google library he's using as he explicitly performs no network requests.

Calm down Paul!

No one can tell you which one is better because it's personal preference.

Besides, there is only one person who attempted to change the display and that info is in the Wiki/Files section of the forum (Herman's work).

Now's the time to experiment - look at the specs and buy the display that matches the interface - simple.

Search the 7500+ messages - hopefully, you'll find more info.

Do the LCD modules you selected have 18 pin connectors as described in the wiki?

You need the resistive touch panel.

Unless I misread the diagram those displays have 40 pins.

Good luck on your search.

Did you check that they use the same controller?
