Component Measuring Adapter for NanoVNA

This page is work in progress and may be updated frequently (last update : 2021-11-10 14:37 UTC). 

Introduction

As a hamradio homebrewer I often use my NanoVNA to measure filters, antennas and crystals. But a NanoVNA is much more than that, you can also measure components with it. For that I  use a improvised adapter which plugs into my QRP-Labs filter adapter for NanoVNA.

A small strip of PCB is cut to the size of a QRP-Labs adapter PCB, the copper on one side is separated in half and one half is separated again in the middle. A small piece of experiment PCB with holes is used as a template to drill the 16 holes for the female headers.

To connect various sizes of components, it contains of a 2x4 female header connected to ground, a 2x2 female header connected to CH0 / IN and a 2x2 female header connected to CH1 / OUT.

Top and bottom are connected to ground (note the IN and OUT section are cut free from the ground plane.

And it fits perfect to my QRP-Labs filter adapter for NanoVNA.

But you don't need a QRP-Labs filter adapter for NanoVNA to test components. You can also buy a NanoVNA Testboard Kit on various online sales platforms like AliExpress which can also be used to measure components.

But because my improvised adapter works, and I already have designed  1206 PI network Attenuator PCB's  I didn't buy one. 

So I designed my own

But hamradio is also building your own tools and improving them. So on a free afternoon, I designed one for my own and just like my QRP-Labs filter adapter for NanoVNA, it has build in calibrations support to get the maximum out of it.

With the design was ready,  I ordered a set of prototype PCB's and now I'm waiting for delivery.

 

PCB's in the house

After just 6 days, the postman delivered a small batch of PCB's (25 pieces which I ordered at JLPCB's) for my NanoVNA new component tester.

So I picked the components and placed them (excl the SMD resistors) to see how it would look. For now I'm very happy with the result.

I assembled one, tested it, and the results looked good. Very happy with the end result.

So I started writing a construction / usage manual for it.

I wrote a manual on the construction and how to use it. This manual can be download here : link to manual (PDF)

Base plate

Because it's based on the my QRP-Labs filter adapter for NanoVNA I can re-use the 3D printed base plate again. 

I made the design publicly available so you print your own but licensed it Attribution-NonCommercial-NoDerivs 3.0 Unported (CC BY-NC-ND 3.0).
Meaning :

  • NonCommercial — You may not use the material for commercial purposes.
  • NoDerivatives — If you remix, transform, or build upon the material, you may not distribute the modified material.

It's not to be childish but it now happened a few times that a 3D design I made was sold by other people just because is was "Open source, so I can do anything I want with it" without any credits or even a token of appreciation

 

When you want it to be used Commercial, please contact me.   

 

Where to buy 

I ordered a small batch of PCBs will build a few prototypes.  

The left-over PCB's of this small batch will be sold through this For-Sale page on my website.  When they are sold out and there is a demand, I might be ordering a new batch of PCB's to sell them, make new kits or even sell full assembled adapters. So when they are sold out and your interested, let me know.   

The design will be publicly available (use contact form to request GERBER files) so you order your own PCB's at OSHPark or a other PCB factory of your choice, but licensed it Attribution-NonCommercial-NoDerivs 3.0 Unported (CC BY-NC-ND 3.0).

When you like the design and PCB's. a small fee as a token of appreciation / commission to support my work is very appreciated (see : Support & Tip Jar).
