Re: Wait for NanoVNA-V2.....
Do you remember those huge Fresnel lenses that used to be sold so you could 'enlarge' your 14" TV to 30" or more?? ?Maybe someone should design a 3d printed housing for the NanoVNA with a Fresnel

Re: Wait for NanoVNA-V2.....
Larry, Thanks for the clarification. Too bad there isn't a similar 4 or 5 in display, although at that size I would think you would want more pixels instead of larger ones for better resolution. -

Re: Any plans to publish the NanoVNA board files
I made both versions. After communicating with edy555, I changed the nanovna label to nanovna-h label. You can check the nanovna-h label under the battery.

Re: Wait for NanoVNA-V2.....
I recently replaced my display with a 3.2 version that works with the same software (see the Wiki Files). Replacement with an even larger display is not possible without rewriting the firmware. And

Re: My NanoVNA is not recognised by DFUse when using V 0.2.3 firmware
Just as well; source includes comments like: "this is limited to stm32f405RG and will fail for other future chips." Well, it is newer than Android apps that I worked on, pre-Gradle and pre-IntelliJ
