Apos x OLKB Preonic — Individual Components

Note: These are extra components intended to be used with the Apos x OLKB Preonic mechanical keyboard.

Keycaps

These XDA profile keycaps are made from PBT with dye-sublimated legends for readability and strong resistance to wear and shine. The uniform profile keeps every row at the same height, making them a natural fit for the Preonic’s ortholinear layout and flexible custom key arrangements.

PCBA

The PCBA package includes both the Preonic Rev 4 main PCBA and the dedicated LED PCBA. It supports an RP2040 microcontroller, full per-key RGB lighting, integrated underglow, up to ten rotary encoder positions, improved double-detent encoder compatibility, universal USB daughterboards, external RGB connections, SWD breakout pads, and QMK firmware.

Case

The case package includes CNC-machined aluminum top and bottom sections plus an acrylic LED diffuser. The aluminum case creates protective housing for the PCBA, while the diffuser spreads the integrated RGB underglow into a smoother band of light around the case.
