Larger Display

 

Has anyone played with finding a larger display for the nano-vna.
Jim
 

Hugen has commented there is a 3.2" display that is compatible with the current device.
Anything else would need new display drivers in the F/W

I was considering that. Looking at some from the adafruit site. Also full size connectors. I wanted to take a look at the code first as there is probably some display adjustments to be made.

I have ordered a NanoVNA-F with 4.3 inch display.

There is alo a special newsgroup:
/g/nanovna-f
 

Recently I have replaced my 2.8" LCD with a 3.2" version. Document is in the Files section.

Great work!

The ILI9488 displays are 480x320, so twice the pixels, and also come in 3.5
and 4.0 inch LCD sizes. They are controlled very similarly to ILI9341,
with the main difference being the ILI9488 has 24-bit color input and the
ILI9341 has 16-bit color input. I intend to use it on my VNA design.

Hi Daniel,
partialy true... ILI 9486/9488 have different key commands compared to 9341. Both does support 16bit pixel data but via parallel interface, via native SPI you can only use a strange 8 bit format or 24bit . Nice SPI interface with 16bit pixel data is available on raspberry pi 3.5/4" modules and have spi to parallel converter on board.
3.5" Raspberry pi lcd is very cheap.
