Ultra-Compact 40% Layout

The Epomaker TH40 is a 44-key mechanical keyboard with a 40% layout that removes the number pad, arrow keys and traditional top row. A split space bar places an FN key between 2.25u and 2.75u bars to reduce finger travel. The plastic case measures 10.1 in by 3.8 in by 1.4 in and weighs little for easy transport.

QMK/VIA Programmability & Tri-Mode Connectivity

This keyboard suits programmers and typists who want four switchable layers, three of them programmable through VIA software without reopening it each time. It connects via Bluetooth, 2.4 GHz wireless or USB-C for use across desktop, laptop and mobile devices. Buyers who need dedicated arrow keys, a function row or a numeric keypad should look at larger layouts.

Factory-Lubed Wisteria Linear Switches

The board ships with pre-lubed Wisteria linear switches mounted on a gasket structure and paired with south-facing per-key RGB LEDs. The linear action and factory lubrication deliver a smooth, quiet keystroke suited to long typing sessions. Users who prefer tactile feedback or clicky switches will need to swap them using the hot-swappable sockets.

Questions about this item

How do I install the 2.4 GHz dongle and what step do users often miss?

Plug the included 2.4 GHz dongle into a USB port, then press the keyboard's mode key to select 2.4 GHz; the step often missed is toggling the mode instead of assuming it pairs automatically.

What maintenance will the Wisteria linear switches need later?

The switches are factory-lubed, so no re-lubing is required; if a switch fails, use the hot-swappable sockets and the extra switches in the box to replace it without soldering.

What limit appears first during long RGB sessions?

The 16.8 M RGB backlight draws extra power, so on Bluetooth or 2.4 GHz the battery will deplete faster than the LEDs reach any thermal limit.
