Epomaker TH40 vs Keychron V5 MaxUltra-Compact vs Full-Featured

The Epomaker TH40 is specifically designed for small desks. Its 40% layout measures only 258mm in width, which is significantly smaller than the Keychron V5 Max's 392mm length. The TH40 saves substantial space by eliminating the number pad, function row, and navigation cluster.

Yes, the Keychron V5 Max listing states it is compatible with macOS, Windows, and Linux. It includes a system toggle switch and an additional set of keycaps for macOS, allowing you to save separate layouts for each operating system directly on the keyboard.

Yes, both the Epomaker TH40 and the Keychron V5 Max feature hot-swappable PCBs. This means you can change the mechanical switches without soldering. The TH40 supports 3-pin and 5-pin switches, while the V5 Max is also compatible with most 3-pin and 5-pin MX-style switches.

The Keychron V5 Max has a larger 4000mAh battery compared to the Epomaker TH40's 3000mAh battery. According to Keychron's specifications, the V5 Max can last up to 190 hours with backlighting off. The TH40's actual battery life is not specified in the provided details.

Both keyboards offer a 1000Hz polling rate in their 2.4GHz wireless and wired modes, which is suitable for gaming. The Keychron V5 Max listing specifies a 90Hz polling rate in Bluetooth mode, while the Epomaker TH40 listing specifies 125Hz for Bluetooth. For the best gaming performance, using the 2.4GHz dongle is recommended for both.

Both keyboards come with PBT keycaps, which are more resistant to shine than ABS. The Epomaker TH40 uses dye-sublimated PBT keycaps in a Cherry profile. The Keychron V5 Max uses double-shot PBT keycaps in an OSA profile, which the manufacturer describes as having OEM height with an SA-like spherical shape.

Yes, both keyboards support full programmability via the open-source QMK firmware and VIA software. This allows you to remap every key, create macros, and set up multiple layers. The Epomaker TH40 has four switchable layers, three of which are programmable.

The Keychron V5 Max has an edge for modders. It is available in a barebones kit, meaning you can choose your own switches and keycaps from the start. It also features screw-in PCB stabilizers, which are generally easier to tune and modify than the plate-mounted stabilizers listed for the TH40.

The Epomaker TH40 does not have dedicated arrow keys. Arrow functions are accessed through a function layer, typically by holding a modifier key (like Fn) and using other keys (often WASD or IJKL). This is a standard characteristic of 40% keyboards to save space.

Both keyboards use a gasket mount design to provide a softer typing feel and reduce acoustic resonance. The Epomaker TH40 description mentions it uses Poron plate foam, an IXPE switch pad, and bottom Poron foam. The Keychron V5 Max listing mentions it uses sound-absorbing foam and a polycarbonate plate as part of its gasket mount system.

Only the Keychron V5 Max includes a control knob, which can be used for volume adjustment, scrolling, or other functions programmed via QMK/VIA. The Epomaker TH40 does not have a knob; volume control would need to be assigned to a key combination on a function layer.
