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.

Need help with name of component (Naked USB Flash drive?)
1) Get https://www.adafruit.com/product/3500 Instantly start controlling built-in RGB LED, and LED strips with basically no programming. 2) Stop playing with Python, that won't get you anywhere close to where you want. Switch over to Arduino and learn C++. 3) Understand the bootloader code https://github.com/Microsoft/uf2-samdx1 - then write an app to allow R/W blocks on built-in flash, while also playing with LEDs. 4) Since it only has 256K flash, you'll need to hook up some flash chips if you want more space. (Too many types to list, depends on your cost vs speed trade-offs.)

Electronic leadscrew, or full CNC?
And it looks like pendant support was 'enabled' last year in grblHAL, but I don't see the "I'm with stupid guide" that I would need to connect it.

Budget budget CNC controllers - what's the bottom line?
You might want to look at grblHAL. It is the 32-bit evolution of Grbl. I make a 5 axis breakout board for it based on a Teensy 4.1. It supports step rates up to 400 kHz which allows you a lot of freedom in selecting microsteps and high speed rapids. All in with the Teensy, it costs about $65-70, depending on options. Here is a gallery with a number of machines based on grblHAL. More about grblHAL here. It is actively being developed with people adding features and porting to new processors (RaspBerry Pico is coming).
