MIIIW BLACK IO uses black transparent keycaps to cover the fully transparent Kailh Jellyfish switches, giving this compact 83-key mechanical keyboard a sense of mystery and uniqueness. Thanks to the hot-swappable PCB, the keyboard allows you to install or change the switches with no soldering required. It supports three connection modes and is compatible with Windows, Mac, Android, and iOS systems, so you can easily switch from work to play. Customizing your keyboard is fun. Thats why the BLACK IO features a programmable layout via QMK and VIA. Plus, it has an N-key rollover, which means no matter how fast you type, it can keep up with every keystroke and has multiple RGB backlight modes that allow you to set it to a single color or light it up with a rainbow wave.
