Re: Voltage sensing diode
I didn't have an SMT diode so just used an axial 1N4148. Can be done if one forms the leads with fine-point tweezers. It works fine. Also, used the clipped lead wires to make little hooks for

Re: Is it possible to do a display driver swap?
So what I want to do is using another display, for example a display with an ili9486 controller instead of the ili9341. What I want to know is how hard it is to modify the software. Do I just replace

Re: Voltage sensing diode
I have two Nanos and neither had the diode. I added the diode shown on the schematic an SD103AWS SMD part and then the battery indicator will work fine. Note it interferes with the battery connector

Re: I added copper shields and it didn't turn out as expected ...
Jeff,, Thanks for taking an interest. The answer is no. I'm very careful and took into account all the SMD parts locations. No, I don't see how I could have done that. I made sure that the edges of

I added copper shields and it didn't turn out as expected ...
To the first nano I got (the one with the white 3D printed case) I added my own carefully-made copper shields. I recently got another Nano (the one with the orange case). It also came with no shields.

Voltage sensing diode
Are some NanoVNAs shipping with the D2 voltage sensing diode installed? None of the ones I have in hand populate the diode and I did not notice it any of the online photos of the interior that I

Re: Newbie
From what I can tell here, most all the NanoVNAs you order work. The first thing to watch out for when ordering lowest cost is "no battery included". Most people will need this and unless you can buy
