Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Portable Signal Generator?
Are you trying to build your own nanoVNA? There are many different versions of the nanoVNA on the internet, google "nanovna source" and see how they implemented the signal generator part.

Survey: Help us design a VNA for hobbyists and professional users
Wanna do the community a favor and fork edy555’s repository here? Study the issues and comments in the repo along with the NanoVNA’s complaints all over Amazon. Coming up with these decisions on your own might serve to be vastly more valuable than letting the community tell you what to do.

Where to get a good NanoVNA v3? I'm fine with copies. I just want it to work properly.
I bought mine from Nooelec. They're listed as an official distributor on edy555's GitHub repo.

Writing bootloaders for microcontrollers
Here's a bootloader "library" that might be useful. You need to add your own code to get the actual firmware image from somewhere (UART, an SD card, or whatever), and then you just pass it off to the "library" for flashing.

Difference between a programmer and a USB-UART adapter
Yes, unless you have something like an STM32 with a built-in bootloader. This can be used to update the regular bootloader. For example, this bootloader is capable of jumping to the built-in bootloader from software (as opposed to the "regular" method of pulling certain pins high or low at reset to cause the processor to run the built-in bootloader from ROM rather than the regular bootloader from flash).
