Rev 4 OLKB Preonic

Apos is an Oakland, California company of enthusiasts and an authorized retailer of audiophile equipment, desk accessories, and high-end enthusiast products. They matter to this site for one specific reason: they are the ones bringing the OLKB Preonic back as the Rev 4, after Drop's store closed and left the Planck and Preonic without a retail channel.

Status (July 2026): The Preonic Rev 4 has not launched. The product page shows a waitlist signup instead of a buy button, and Apos has not published a price, colorways, switch or keycap options, or a ship date. Everything below comes from the spec sheet on that page.

A 5×12 ortholinear grid with a dedicated number row. Apos and OLKB rebuilt the PCB from scratch for this version: new 4-layer hot-swap PCB, anodized CNC aluminum case, per-key RGB plus underglow, up to ten encoder positions, and an RP2040 running QMK.

The "What's included" section on the listing reads, in full, "Preonic Rev 4 keyboard kit." That is the whole description, with no mention of switches or keycaps, which is normal this early in an interest check. What we'd like to see is the kit shipping with keycaps and a cheaper barebones version for people who already have a set. Our ortholinear keycap list has sets that fit a 5×12 grid.

What is Apos 𝒙?

Apos 𝒙 is Apos's community design platform. Designers pitch ideas, community members sign up to audition prototypes, and Apos supplies the resources to get a design produced. The community is involved from concept through final tweaks.

The Preonic Rev 4 is going through that process, which is why it is sitting as an interest check rather than a dated launch. Specs like the ten encoder positions can still move before it ships.

Other Apos keyboards worth knowing about

Apos sells plenty of keyboards that have nothing to do with ortholinear. These two are the ones that overlap with what we cover.

Apos x Community 40% Micro Keyboard with twin encoder knobs

Apos x Community 40% Micro

Another Apos 𝒙 project: a compact 40% with twin encoder knobs and QMK/VIA support. Like the Preonic Rev 4, it is an interest check with a waitlist and no price posted.

Who Apos is, in their own words

Apos describes itself as "a company of enthusiasts on a mission to bridge the gap between designers, the community, and the world's best brands." They partner directly with the brands they carry, which is how they guarantee authenticity, and they back purchases with:

  • Free shipping
  • Lowest Price Guarantee
  • Apos One-Year Transferable Warranty
  • 45-day return policy

The warranty transfers with the keyboard rather than staying with whoever bought it, which is useful in a hobby where boards get resold constantly.
