Compact 75% Layout

The Epomaker Luma84 is a 75% QWERTY ANSI keyboard with 84 keys built around an anodized aluminum case and a PC plate. It uses Gateron low-profile Red linear switches with a 50±15 gf trigger force, 1.7 mm pre-travel and 3.2 mm total travel. Double-shot and dye-sub PBT keycaps in a DSA low-profile shape sit on a gasket-mount structure with sandwich foam, switch pad, sand-enhancement pad, switch socket foam and bottom sound-absorbing foam.

Battery Life and Latency

A 3000 mAh battery powers the board for wireless use. Latency measures 4 ms over wired USB, 12 ms over 2.4 GHz and 24 ms over Bluetooth 5.0. Polling runs at 1000 Hz on USB and 2.4 GHz, dropping to 125 Hz on Bluetooth. N-key rollover anti-ghosting is supported across all connection modes.

QMK VIA and Hot-Swap

The keyboard is fully programmable through open-source QMK firmware and the VIA graphical interface for macros, remaps and layer changes. Hot-swap sockets accept both 3-pin and 5-pin mechanical switches so switches can be changed without soldering. Per-key south-facing RGB LEDs provide static and dynamic lighting effects in single-colour and full RGB modes.

Questions about this item

How do I pair the keyboard with a PC over Bluetooth 5.0?

Turn the keyboard on, hold the Bluetooth key combination until the indicator flashes, then select the device in the OS Bluetooth menu; the 125 Hz polling rate applies in this mode.

When will the Gateron Low-Profile Red switches or stabilizers need replacement?

The switches are hot-swappable for 3-pin and 5-pin mechanical types, so individual switches can be pulled and swapped without soldering whenever feel degrades.

At what point does battery life become the limiting factor during long wireless sessions?

The 3000 mAh battery powers the keyboard until depleted; runtime varies with RGB brightness and the active wireless mode (2.4 GHz or Bluetooth 5.0).
