Moving to a RTOS on the RP2040

I've deployed a few instances of these things for various tasks and I've always been annoyed by how they work. But this is a consequence of having great performance right?

Network switches are simple devices, packets go in, packets go out. Luckily people have figured out how to make it complicated instead and invented managed switches. Usually this is done by adding a web-interface for configuring the settings and see things like port status. If you have more expensive switches then you'd even get access to some...

After enjoying making a PCB in KiCad the annoying for me is always getting a case designed to fit the board. If I'm lucky I don't need many external holes to fit...
