Ultra-Compact 40% Layout

The Epomaker TH40 is a 40% wireless mechanical gaming keyboard with 44 keys in a purple finish. It uses Wisteria linear switches and a gasket mount structure for a compact typing experience. The split space bar includes 2.25u and 2.75u bars with an FN key between them to reduce finger travel. This layout suits users who want a minimal footprint for portability or desk space.

Sustained Typing and Gaming Feel

Factory-lubed linear switches and south-facing per-key RGB LEDs deliver a consistent thocky sound profile during extended sessions. Full N-key rollover ensures every simultaneous press registers without conflict during fast typing or gaming. The gasket mount and plastic case absorb vibration over long periods. Three programmable layers via VIA allow function access without leaving the home row.

Installation and Common Issues

Connectivity works through Bluetooth, 2.4GHz wireless with the included dongle, or the detachable USB-C cable for wired use. VIA programming requires importing the TH40 JSON file into the online VIA editor before key remapping or macro creation. The 40% layout lacks dedicated number, arrow and function rows, so users unfamiliar with layer-based navigation may find the learning curve steep. Hot-swappable sockets accept 3-pin and 5-pin switches for easy switch changes.

Questions about this item

Does the 44-key gasket-mount design with lubed linear switches stay quiet and cool during all-day sessions?

The gasket mount and factory-lubed Wisteria linear switches produce a muted thock sound, while the plastic case and low-power tri-mode electronics generate minimal heat during extended use.

What must I already own to use the Bluetooth, 2.4 GHz dongle and USB-C wired modes?

You need a device with Bluetooth, an open USB-A port for the included 2.4 GHz dongle, or a USB-C port for the detachable cable — no extra drivers are required.

Will the split 2.25u and 2.75u spacebars with the FN key between them work with my existing keycap sets?

Standard MX-stem keycaps fit the switches, but the non-standard split spacebar sizes mean most aftermarket sets will not cover both bars without a dedicated 40% kit.
