(PR) Apos Launches Preonic Rev 4, Bringing Massive Updates to a Cornerstone of the Custom Keyboard Movement

Apos today announced the launch of the Preonic Rev 4, the newest generation of Jack Humbert's influential ortholinear keyboard and the most significant modernization of the platform in years.

The Preonic traces its lineage to Jack Humbert, founder of OLKB and the engineer of the Planck keyboard, whose work helped shape the modern custom mechanical-keyboard movement. Humbert was an early advocate for smaller, programmable keyboards built around layers rather than an ever-growing number of physical keys. His work on the Planck also helped give rise to QMK, the open-source firmware platform that became fundamental to custom keyboard design.
