A prior hardware rev of the H4 does flashing while charging, and steady-on when fully charged (mine does that)

It could be that the charging source is pulsing (e.g. from an internal thermal limit perhaps). It's not like all USB power sources are fully compliant. Look at the huge design difference between

Then what does flashing mean?

I saw that, but it does not explain why this user appears to be seeing a different behavior . . . . -- Sent from my Android device with K-9 Mail. Please excuse my brevity.

Hugen is the manufacturer of the -H and -H4 and he replied to this post yesterday... /g/nanovna-users/message/27085 Roger

What is the trick on your website to get it to be in English. I selected English, but it still is in Hungarian or what ever the language is by default. 73, Cliff, AE5ZA

The spec sheet for the MCP73831 charge controller shown in the NanoVNA hardware diagrams that I find (https://ww1.microchip.com/downloads/en/DeviceDoc/MCP73831-Family-Data-Sheet-DS20001984H.pdf) only

The v3.4 hardware is not that old (NanoVNA started with Chinese production in 3.0). You can see more information on my website. http://ha3hz.hu -- Gyula HA3HZ

OK we need absolute clarification from like the manufacturer or something here. Mine NanoVNA-H4 First time I used it i did the charge before use. I was "Told" that when charging the red led will

Hello, Does anyone know if the jumbo font used in the latest 'H' firmware (for 2.8" devices) has made it into the 'H4' or 'F' firmware (for 4" display devices) - as of March 2022? See the attached

I have one of the older -H version 3.4 I was wondering if anyone has ever done a component-level upgrade of the board to the latest hardware version, or if a change log of sorts exists?

On mine, the red LED indicates charging, and it goes out when full. - Tim -- Sent from my Android device with K-9 Mail. Please excuse my brevity.

Yes. The most recently released version is v1.1.0. If you are interested in the details of firmware development, you can find a description on my website in pdf file or more on the forum wiki here. --

Yes. The hardware is NanoVNA-H by Hugen, while the firmware is NanoVNA-D by Dislord, which is suitable for operating -H to -H4. -- Gyula HA3HZ

This may be a dumb question but it seems I have an older version of nanovna that has 0.8.0 version, that is the last version of EDY555. Can I jump to another tree? or if there is a newer version could

Hi, I am currently using DiSLords v1.0.69 on my nanoVNA H. To keep up-to-date I looked around for the latest DiSlords software v1.1.00 and found the "NanoVNA.H.v1.1.00.dfu" file in the GitHub pages

Thank you very much to all. Each one of you has made an interesting contribution for me. Thanks again /EA7HJ - Antonio

Ditto. I really don't understand why the NANO's do not display real and complex values for the impedance. Jim, I just stick with basic units: Ohms, Hertz, Farads, and Henries. Simply utilize the
