Rotate Display 90¡ã #improvement
Hi, i like m nanovna, but unfortunately the display is not the best one. The original alignment of the display is portrait, but using it in landscape looks not so good. Is it possible to rotate the

Re: nanovna often not powering on when on battery #batteries #battery
Hi Marcel, If I understand it, searching for "NanoVNA doesn't want to start" in forum discussions may be a solution. It's a good idea to read these and it might help. As far as I remember, there was

Re: First PCB pictures of the V2
If you can see the images I posted you'll see it runs the same UI as the Nano ;) And it's compatible with the most widely used Nano software, nanovna-saver. The STM32 we are using is of the same specs

I have been pursuing other interests and muted several topics and hashtags here. You, Larry, Erik, Alan and others do fine; I should add more "like"s. The USB shell `sweep` command already supports

Re: First PCB pictures of the V2
If compatible with neither nanoVNA (nor, sadly, VWNA) software and lacking STM32 support, then substantially as unrelated to this group as any other low cost VNA.

Re: First PCB pictures of the V2
It's 201 points per save location, 5 save locations total. The command interface is *not* compatible with the original Nano, but I already have a working patch for nanovna-saver which I will upstream

Re: First PCB pictures of the V2
Finally got 201 point sweep working. You can now configure arbitrary number of sweep points between 2 and 201 (on-screen). The max sweep points over USB is still 1024. Memory and flash usage: Memory

I was just looking over the image hugen uploaded a few days ago for the new rev 3.4 board at https://github.com/hugen79/NanoVNA-H/blob/master/doc/NanoVNA_Rev3.4_PCB.jpg . Looks like he delivered on

Hi Herb - It would require some additional code for a single firmware to dynamically detect whether installed with more flash, then conditionally increase that 101 limit. Of course, that additional

I too have power problems, perhaps not quite the same as yours. I also have two units, a black and a white.? The black one behaves normally most of the time but occasionally will switch off.? I

hugen, per your GitHub info: "This is my attemp to port the STM32F303CCT6 to this popular NanoVNA project. The benefits are larger SRAM 40KB from 16KB, larger flash 256KB from 128KB, faster CPU clock

Re: Plain speaking about the Reference Plane
Establishing a "measurement plane" makes the impedance or admittance displayed on the VNA valid at that specific point. For example, you want to know what the impedance is at the input of some device.
