Re: what does your NanoVNA circuit board look like?

 

Folks:

Regarding batteries, I ordered mine on Banggood, and the description
contained this caveat:



* Batteries are not included because of the safety of international
transportation. But we have reserved a power management IC, you can
weld your own batteries.
Or use other power sources, such as power bank, to supply power to it
through USB interface.
*

Sure enough it doesnt charge, and as they advise above, I run mine off a
USB battery bank. I havent cracked the case to look, but I imagine I will
add a battery sooner or later.

I just received my NanoVNA yesterday and it was shipped without the
battery. I noticed there are unused pads directly below the coil, one of
which connects to VCC batt. There is also a spot for a TF card slot.
I would appreciate if other NanoVNA owners could post photos of their
boards for a comparison to see if there are different versions being sold.
Also, does anyone know if there is a touchscreen calibration routine
available?
Mine is way off.

Thanks
Larry
