Is there a wifi/bluetooth/radio keyboard/mouse adapter?

Question

Keyboard

Hello.
There is a usbish keyboard, but because of the sea of ​​\u200b\u200bcords, I want to get rid of a few wires. Since the keyboard is ergonomic and I don't want to change it, I'm looking for an adapter for wireless communication. So that one part is inserted into the computer, and the keyboard is inserted into the second part or soldered into the keyboard itself.

If you want to stir up your power and make a scarf with batteries inside the keyboard case with this

Answer 2

A normal wireless keyboard works 1-2 years on one set of batteries. A normal mouse - six months or a year, if you do not play with toys.
Your "keyboard is ergonomic and you don't want to change it" is not optimized for power consumption, and will gobble up 3 batteries (you also need to provide USB power, it's 5V + - 0.5V) per day, if you're not lucky, if you're lucky - in a week. So it's a pointless event.
Strain the wires - buy a normal wireless kit, save time and money.
