2 arduinos with a serial link between them.
(I would use it to use a laptop keyboard on a headless computers).
I am looking for an easy solution, it does not have to be the cheapest.
ChatGPT points me to Arduino, but as far as I can see, there's no arduino with 2 usb ports. It also points me to Raspery pi zero, but that's a computer, not a microcontroller, so not sure if it's suitable.
If anyone with experience can give me some pointers, it would be greatly appreciated!
