Converting a USB wired keyboard into a wireless keyboard

I was looking for a way to convert my wired keyboard to wireless and finally I succeeded. It even integrates Bluetooth 5.3, wireless 2.4, and wired connection modes, and supports quick switching between 8 wireless devices. The modification process is so simple. So I made this video. This is also my first YouTube video, and I think there are many people like me who need this module. So I have put wscome's website here: https://www.wscome.com.
This is my first YouTube video. If you like it, please subscribe to my channel. Your support means a lot to me, and I will strive to create more and better videos like this.
If you have good suggestions, I'd be happy to listen and make improvements.
