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.

Show HN: I spent a year designing an low profile, minimal mechanical keyboard
Depends a lot. If you want it fully assembled, you have to go to larger fab houses like PCBway, and spend a few hundred bucks on a 5pc batch. If you can hand-solder some parts (in this case, the Bluetooth module and the USB connector) and design the rest around jlcpcbs libraries, you can get away with 20-30USD per unit (MOQ of 5) plus shipping/customs. Then add another 10USD for the bluetooth module and USB connector.
A simpler wired design like my E80-1800 (https://github.com/ebastler/E80-1800) can be completely assembled by jlc for ~30ish USD per unit.
Oddly enough, small-batch prototyping at jlc can be cheaper than medium sized (50-150 pc) runs at other fabs.
Hope this doesn't sound like an ad, I've compared a lot of prices and nobody came close to jlcpcb, but With their limitations (limited stock, limited finish/color choices, frequently chnaging stocks and component prices) and sometimes far-from-ideal QC (some scratches can happen, in rare cases even missing components that were present in the BOM) they are not really my first choice for production runs. For prototypes or small unofficial-ish batches with a few friends though - god tier.

I built a keyboard PCB and wrote firmware for it in Rust
While waiting on the switches and keycaps, I started writing the firmware. I started with my rp2040-template I made recently, and drew heavy inspiration from the Rustykeys project I mentioned before.
