Mike, looking at the photo of the shields and how they mount, there is nothing that is visible to me that is obviously wrong. I say this because the ch1 shield is mounted on pads that seem to be tied

Just found it and started reading. Found a nice mod for a DFU switch. Go to junk box, find last switch, break switch. I’ll have to find a new switch but I am reading through the wiki now. Thanks

I mentioned some time ago that my HP LCR meter could show impedances in many ways - I think there mist be about 20 ways. It doesn’t display S-parameters though. If its any help, I could do a single

To replace the display with ili9486, you need to modify the ili9341_init_seq[] at line 151 of ili9341.c and change the LCD width and height at various files. But if you want to replace with ili9488,

Hmmm ... thanks for that. Let me play some more tomorrow and see what I can do.

Hi Mike_nano, Jeff... One difference I note from prior photo's and shielding is the connection of the shield itself TO THE SMA CONNECTOR BODY. Each shield was returned to ground via the SAM. This

Hi Martin, Yes. The only issue I see is the display of X as pF (or maybe nH or uH) in any case, all cases will be the parallel equivalent admittance (impedance). Rune and I discussed and in all cases

Arduino folks do this sort of thing: https://forum.arduino.cc/index.php?topic=513245.0 Practicing on e.g. a blue pill with Arduino_STM32 would seem a safer approach.

An Amazon customer reports that the US$65 Hawking HMPS1A works with a USB to serial converter. https://www.amazon.com/dp/B00NMUJ4R0 Power in is 5VDC, could be portable by USB power bank.

Hi DougVL - I think there is no 64-pin STM32 micro that supports USB OTG, so a bluetooth "dongle" that supports SCC profile and USB OTG is wanted. There are quite a number of wireless adapters with

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

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

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

Eu adicionei o diodo 1N4148 (D2 proximo ao conector bateria). Atualizei o FW 0.2.3-20191008

And i did

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

Mike, any chance that the shield is shorting out C26 or C27? Jeff, k6jca

That's a great case, I'm going to print one today :)

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.

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
