What is it for?

Hasu USB2USB converter allows you to customize any key on any keyboard. It is a macro keyboard that can be taken anywhere and is a productivity tool.

what are the benefits

• Turn any keyboard into a complete macro keyboard, and you can modify the function of any key at will
• Condensate complex shortcut keys into one button
• Multi-layer key definitions can be saved. Let one macro keyboard serve as several macro keyboards
• Can send mouse signals to the computer through the keyboard
• Send system function keys (power-on lock, etc.)
• Send media control keys (volume control, etc.)
• Control keyboard backlight
• The meaning of custom keyboard indicators
• Create more fancy functions by combining it with AutoHotkey on the computer side
• It’s almost impossible to choose a keyboard, as long as it’s a USB keyboard, you can use it

How to develop it

This converter is compatible with TMK and QMK firmware, but it is recommended to use TMK firmware

You need to have a basic knowledge of C language -> TMK document portal or use the online editor to quickly make simple key modifications

scenes to be used

• Heavy users of shortcut keys - no need to memorize so many shortcut keys now
• Users who like to use other key positions - don't like qwerty keys? No problem, plug this in and it will become the key position you want.
• Mini Keyboard Users – Want special keys but don’t have them on your keyboard? No problem, you have all the keys now
• AHK users - open a new world with one click
• I don’t know why, but users who need the F13--F24 keypad - well, few people know that there are 24 F keys now.
• The lowest-cost solution for a macro keyboard—just find an old keyboard that’s under the box

Perhaps what TMK firmware can provide is limited, but what C can provide is unlimited.
