how to resolve n-key rollover?

Question

Hello,

i use a logitech keyboard and have the issue i can't press 3 buttons next to each other, neither 4-5 ofcourse.

i was wondering if i could somehow open it up and rerout the keys so that they'd for example the 5 key would be treated as if i were pressing the w key so i can press multiple keys at the same without it technacaly being next to each other.

thanks so much in advance,
Logical.

Answer 1

True N-Key rollover requires a diode in series with each key switch so they cannot interact.

It is extremely unlikely you would be able to do such a change to an existing keyboard.

Answer 2

You'd be completely replacing the electronic components in the keyboard, so you might as well get a new one, it can't just be changed.

Answer 3

Better to buy a $35 USD keyboard with full all key rollover. I have many that do that, and for a few $ more, illuminated. And for a few $ more, full RGB and programmable colors on each key, and with multiple macros if you get the free download software and use it. See:

Very nice unit, good mechanical keys, full N key rollover, 104 key anti-ghosting, many colors, solid construction, prompt delivery at excellent price if you want those features. Paid a lot more for similar boards.

Answer 4

with rerouting i mean redirecting the paths of the keys physicaly or something.
