I understand how to use the Nano-VNA to measure a crystal's frequency. yes, and it's a lot easier, because the LC circuit is lower Q, so you don't have to worry about "missing" the resonance with only 101 points. |
Re: Where to buy a NanoVNA H4 HW rev 4.3?
You can buy NanoVNA-H4 from the zeenko store. NanoVNA-H4 is now sold by zeenko in version rev4.3.
It should be noted that the MCU used in the NanoVNA-H4 rev4.3 is the STM32F302CBT6. We have tested that the STM32F302CBT6 has the same RAM and ROM as the STM32F302CCT6. Since no additional STM32F303 functions are used on the NanoVNA-H4, the STM32F302 and STM303 use on the NanoVNA-H4 are identical. |
Re: Questions on Dislord v1.0.69 features
I am just finding this info about the V2plus4 and it¡¯s locked down boatloader and fw author not willing to add ability to disable temperature compensation when CW mode is selected.
So is there no hope other than to try and buy a different V2 variant and sell this one ? |
Re: NanoVNA and PC.
In the absence of solutions I have returned to the original Firmware. With it I can manage my NanoVNA from the PC with the usual software (NanoVNA-App, NanoVNA-Sharp, NanoVNA-Server).
Too bad not being able to enjoy the 401 points and manage it at the same time from the PC. Thank you all. Antonio - EA7HJ |
amazon.co.uk NanoVNA with 303 chip
#buying
#nanovna-h4
Hi all.
On amazon.co.uk I bought a NanoVNA from AllAboutFun. It had the STM32F302 chip. I contacted the company and in their reply they said According to your question, we have communicated with the supplier. This is an open source product, and the STM32F303CCT6 chip is currently out of stock. We will definitely only use STM32F303CCT6 in the future. I returned it to amazon and was refunded. I then bought this one for ?114.18 Nooelec NanoVNA-H 4 Premium Bundle - Vector Network Analyzer Kit from Authorized Distributor with 50kHz-1.5GHz+ Portable VNA (4" LCD), EMI Shielding, Calibration Kit, 6pc Attenuator Kit and Much More! Brand NooElec It arrived this morning and I can confirm it has the ST32F303CCT6 chip in it. I hope this helps UK users. Colin MM5AGM |

NanoVNA-F questions
Dr.Alexander Hahn
I've got an used NanoVNA-F by sysjoint.
It shows: Version: Firmware 0.1.5 Frequency: 10k to 1,5GHz Build time: May 17 2020 etc.. My questions are: Which version have I got and is there a new firmware out for it? I've looked at the sysjoint.com page and downloaded the manual, but I see in the files folder of this group that there are new firmware versions. Thanks, Alex |
Re: NanoVNA and PC.
