Nano VNA V2 Plus4 pro

Beware of cheap underperforming clones

As of 2023 there are many badly performing clones on the market. V2/3GHz NanoVNA uses parts like ADF4350 and AD8342 which are costly and clones have been cutting costs by using salvaged or reject parts.

See official store and look for V2 Plus4/V2 Plus4 Pro versions only to avoid getting a bad clone. We have stopped selling V2.2 versions since October 2020, so all V2 hardware that are not Plus or Plus4 are not made by us and we can not guarantee performance.

Hello,

Is a schematic available for this unit ?

I need to identify the surface mount component that is in series with port 1 SMA (port closest to power slide switch)
centre pin. Component is located on the underside of the board under the metal can shield.

I may have damaged this component during the process of replacing the SMA connector.

No guessing please....

Thanks & Regards,
Oli.

Hi, it should be a 10uF 10V ceramic capacitor, to be sure you can send me a photo of the area and I can check.
Thanks

Hi,

Attached picture showing 'TOMBSTONE' component, this happened during the process of de-soldering Port 1 (CH0) SMA, the component has been placed back onto its pads, however i need to measure that its value is correct.

Could you please confirm the PCB through hole diameter for the SMA centre pin via.

Thanks & Regards,
Oli.

Hi, the component is a 10uF 10V capacitor, and the via size for the SMA center pin is 1.2mm.
