It can act as an extremely portable, hardware-keyboard-equipped SSH client to manage servers.

The Q20 allows users to access a terminal, allowing command-line interaction that feels remarkably familiar to a Linux user.

For developers, the firmware is fully customizable using tools like VIA or VIAL, allowing for deep personalization of keymaps and layers.
