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.

node-red: the node-serialport does not work on Termux
Everything works very well, except for one detail: the node-serialport doesn't work in Android+Termux environment. You can't use RS232, MODBUS, RS422, or RS485 !!! See here the open issue,

Using usb-detection with electron v4 on intel mac
Strangely enough it does package fine with electron-builder but does not work in dev mode. The same happens when I try to use https://serialport.io/ which is also another module where you could achieve device detection.

Trying to get access to the USB device in Electron app
We use node-serialport instead of the WebSerial API, since it was only recently that Electron supported WebSerial permission overrides to make things like a 'devices screen' viable. The WebBluetooth APIs are still in a situation where you have to do polling shenanigans to get a full device list. I've found the mutated permissions system leaves a lot to be desired when debugging, whereas the NAPI modules are a lot more straightforward.

I've been streaming hardware driver development using node. If you've ever wondered what's involved when talking to hardware, but were put off by needing to know C or kernel internals, you might enjoy this
It really depends. The stuff I'm doing in this video for example is writing a driver stack for a device called the Bus Pirate. Communication is done over serial (which is easy in node with the serialport library). The bus pirate is a device that allows you to talk to other devices over different protocols, including SPI, I2C, and OneWire (as well as bit banging, where you control some electrical signals directly any way you want using software). So while it's not something you'd do directly in production, you can actually test communication with devices in JS in a fast, iterative, interactive way without having to use a microcontroller. You can actually figure out all of your design decisions there and port your code to the microcontroller later if you're building some kind of embedded system device, potentially saving a lot of time and debugging.

Electron to native hardware
We use node-serialport for USB serial communications. It's included in the transport manager renderer process. The installation guide and docs should be good enough to get you started. Hopefully serialport has prebuilds for the combination of system and electron version you're trying. We had to setup an internal prebuilds system and CDN for our app since we'd often find ourselves ahead of the prebuilt versions for node-serialport. Alternatively you can build from source.
