Hi, welcome to the forum.
Are you using a smart phone that translates some words to links ? It is very confusing.
When you have access to a desktop computer, then you might try to modify your post.
Which keyboard to you have ? A "PRO" or a "TE" ?
This the the BladeMaster TE: https://www.drevo.net/product/keyboard/blademaster-te
What do you want to do with that keyboard ?
Does the keyboard work when you connect it to a computer ? What do you want to do with a Arduino ?
When you use a library or a sketch, please give a link to it or show the sketch.
