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.

can ı use pi pico as usb to ttl adapter
umm i dont want to make it from scratch can ı use this project for this purpose https://github.com/Noltari/pico-uart-bridge

Building the worlds jankiest serial to USB cable from scavenged parts
I think the point was to make something in a pinch with what was already available versus making the most flexible choice.
That being said I use, I'm not the author, https://github.com/Noltari/pico-uart-bridge to turn a Raspberry Pi Pico into a USB to dual UART adapter. It appears as a CDC-ACM device so is supported under Linux and Windows without any 3rd party drivers. I replaced my MacBook Pro with a Thinkpad years ago so I have no idea what the situation is on macOS.

USB in a NutShell
I also recommend USB Made Simple [1], which has similar vibe to this site, but also includes USB 2.0 description and is a bit more detailed on electrical/low level aspects.
For an actual implementation, see V-USB [2] - surprisingly readable software library for bit-banging USB on AVR (Arduino/ATTiny/ATMega)

You can actually bit-bang low speed USB on Arduino [0]. There is even a bootloader [1] for ATtiny. It is obviously not compatible with Arduino, but those tiny boards look too cute to ignore [2]. Also, you can use USB port both for downloading firmware and your application.

What sets the /sys/bus/usb/devices/xyz/power/control file?
Full story I added a microcontroller to a laptop USB cooler because I wanted the device to sleep when the host is suspended. The microcontroller is a DigiSpark ATTiny85 and I'm using the V-USB library to mimic a USB device.
