I got my SAA2 a few days ago, the bare bones version from tindie. BTW, is feedback expected at tindie? Found no mechanism on their page, but I'm not registered, so... I have already ordered a battery

The forum Wiki has all the info you'll need to use the nanoVNA - - Please use it - - There is a link at the bottom of every forum email sent out.

Didn't know there is a Phone App for the nanovna. Where can I find it?

Thank you, avvidclif, agreed on your point (shielding from stray signals and interference). For whatever's worth, my initial state of confusion was to the lack of identifying markings, or accompanying

For S-A-A-V2 situation more easy, it use not only display module, it use PCB board vs module, all PCB board have standart pins 4` ST7796S display module on board

Then possible try build H version vs SD Card support, possibly in future i do it At this moment i get one problem RTC clock on STM32. Then use internal oscillator not run then power off, and not

Aleks, Two suggestions from your photo: 1. Calibrate the unit. The NanoVNA-V2 does not interpolate between points when you change frequency settings and forces you to re-calibrate to the new frequency

Since the F303 was a drop-in upgrade from the F072, all the pinouts remained the same. I have attached portions of the H and H4 schematics - the SD card interface? from the uP is the same for both

If SD card on this board connected as on H4 board, possible compile firmware version for H vs

Did you select the Menu (3 bars, top left of screen)? Trace settings are there.

I have this app working on my phone, but I can't figure out how to change traces. I click on a different trace bubble near the top and it just takes me to the settings for that trace. I'm assuming I'm

The Gekko version of the early nanoVNAs had the solder pads for an SD card slot - look at my forum photo from almost a year ago. I actually added a slot to mine but then sold the unit and bought a

I bought the two units from Amazon Seesii USA with 2 day shipping on the last one. Both units were labeled with 50 KHz starting frequency. But they can start at 10 KHz if that is entered under

DiSlord And with 0.9.2 firmware I get this : ch>? SD_SendCmd err CMD0, 0xFF, 0x00000000 ?CMD0 Ok ?CMD8 Ok ?CMD8 0xAA010000 CMD8 Ok, ACMD41 99 ?CMD58 OCR = 0x0080FFC0 CardType 12 filename

No for H need compile its own firmware, it have about 14kB free flash. Only Fat32 and short filenames need ~10kB (but i don`t test this for H firmware) Also H version not have SD slot on PCB board,

DiSlord, With your comment below, do you mean that the non-ExFat version of your firmware that supports the SD cards should work on an H if I add an SD slot? ...Larry

DiSlord, With this firmware I see : ?CMD0 Ok ?CMD8 Ok ?CMD8 0xAA010000 CMD8 Ok, ACMD41 99 ?CMD58 OCR = 0x0080FFC0 CardType 12 filename VNA_20200525_04212.bmp open 0 close 0 ?Read? speed = 238139

Add support ExFAT filesystem and check work on my SD card All worked, support ExFat need additional 4kB flash and can`t be suppoted on NanoVNA-H (if add card slot in it) But on H4 stiil more flash
