Weren't (true) PS/2 keyboards exempt from all of that? Of course someone could always achieve the first one with enough effort, but it would be adding in lots of things from scratch rather than repurposing the existing hardware that many keyboards have now. And PS/2 had a maximum draw of 100mA so even piggybacking on that would be challenging I'd assume(?) - not an expert. A Teensy which was benchmark for lots of custom keyboards can pull most of that [1]. [1] https://forum.pjrc.com/index.php?threads/teensy-3-6-vs-4-0-m... |
