Ploopy’s smallest open-source trackball now includes a button

The Nano 2 is still designed to offer a “pure cursor experience” and complement a split keyboard setup or a small macro pad. But the new button could potentially turn it into a tiny trackball mouse.

Ploopy has upgraded the Nano with a USB-C port, but as with the original version, you can customize or mod all of its components yourself.

The Nano 2’s single button is pre-programmed to trigger drag scrolling mode so you can temporarily switch the trackball from controlling your cursor to scrolling long documents or websites. As with Ploopy’s other peripherals, the Nano 2 runs the open-source QMK firmware. You customize the button’s functionality using the VIA web app, including making it function as a primary mouse click.
