# Open-Source Trackballs Ploopy A+ is a Programmable Ergonomic Trackball By Amy Duong | Published 2026-08-17 | Art & Design Source: Trend Hunter, https://www.trendhunter.com/trends/ploopy-a References: [blog.ploopy.co](https://blog.ploopy.co/the-aplus-is-finally-here-499)  The Ploopy A+ expands the company's open-source trackball platform with eight programmable buttons, dual rotary knobs and layered controls powered by QMK firmware. Two additional buttons introduced over the earlier Adept design also function as [rotary encoders](https://www.trendhunter.com/trends/the-id360-touchstone), supporting high-resolution vertical and horizontal scrolling while remaining fully remappable through VIA. Gesture controls allow users to hold a button and move the trackball in eight directions to trigger configurable shortcuts, while dual operating layers provide access to navigation functions and on-device settings without requiring companion software. LED indicators display the active layer directly on the device. The [ambidextrous design](https://www.trendhunter.com/trends/seenda-mou302) incorporates a detachable wrist rest that can be removed or permanently secured to the chassis. A Pixart PMW-3360 optical sensor delivers 1,000 Hz polling, while Omron D2LS-21 switches handle button inputs. The [3D-printed enclosure](https://www.trendhunter.com/trends/orbital-works-pathfinder-mouse), firmware, hardware files and assembly documentation are released as open-source resources.
