/// ENGINEERING · DOC.01 — THE BUILD

Every layer, exposed.

No sealed shell, no hidden board. Apollo58 is documented like the precision instrument it is — from the plate stack and OLED displays to the key matrix to the firmware layers. Here is exactly what you're building.

/// BUILT FOR THE LONG HAUL

Made to outlast millions of keystrokes.

You'll type  millions of keystrokes a year on this board. So every layer that takes the load — the PCB, the parts soldered to it and the plates around it — is specified to last years, not seasons.

FIG.04 — PCB / HOT-SWAP
[01] PCB

A board built to be reworked

Precision-fabricated with a protective solder mask and plated contacts, so it takes years of switch swaps and reflashes without wearing out.

[02] COMPONENTS

No corners cut underneath

Hot-swap sockets rated for 1,000+ cycles, a USB-C controller and OLED displays, every one hand-soldered and tested before it ships.

[03] PLATES

Anodised aluminium, standard

Black aluminium top and bottom on every board. Rigid for a firm, even bottom-out, heavy enough that the halves stay put, and an anodised finish that resists scratches.

/// MAKE IT YOURS

Set it up your way

[A] FEEL

Change how it types

Pull a switch, press in a new one. Linear, tactile or clicky — try a new feel on a single key or across the whole board in an afternoon.

[B] LOOK

Change how it looks

Every key takes standard MX caps, so any set on the market fits — sculpted or flat, muted or loud. Re-theme whenever the mood shifts.
