Best for

What will you mostly use it for?

The AULA F75 is the clear choice for general productivity, office work, gaming, and content creation due to its more complete key set and multimedia controls. The Epomaker TH40 excels in specialized scenarios like programming and travel, where its extreme compactness and powerful VIA/QMK programmability are major assets. For modding, the TH40's open firmware support gives it an edge, though both boards are hot-swappable and gasket-mounted.

For gaming

Pick the AULA F75

  • The AULA F75 includes dedicated arrow keys and a function row, which are often used in game menus and shortcuts.
  • Its 75% layout provides more immediate key access without relying on function layers for common gaming commands.
  • The product listing mentions a rapid trigger feature, which can be beneficial for competitive gaming.

“Works exactly as intended and still works as new. The 2.4 GHz Receiver doesn't communicate correctly and isn't reliable but on BT and Cable it works perfectly”

“Overall good little keyboard for the price, other 40s cost more but better quality, also I could not find a few characters mapped on this one, not in manual or online.”
pstraghanVerified buyer· via Epomaker
Critique
“The keyboard is very solid ooverall, but frequently will type two letters instead of one on key press. This is a very frustrating issue and leads to many typos. Without this problem, it would easily be a 5-star keyboard.”

FAQ

AULA F75 vs Epomaker TH40: your questions

The AULA F75 is generally better for beginners. Its 75% layout retains most standard keys like arrows and a function row, reducing the initial learning curve. The Epomaker TH40's 40% layout requires immediate adaptation to layers for numbers and punctuation, which can be overwhelming for new users.

Yes, the Epomaker TH40 will function with its default keymap out of the box. However, to access numbers, symbols, arrow keys, and other missing functions, you must use the built-in function layers. Full customization to suit your preferences requires using the VIA software.

Yes, both the AULA F75 and Epomaker TH40 list Mac and Windows support in their specifications. The Epomaker TH40's VIA software is also noted to support macOS, though some user reviews mentioned initial configuration challenges.

The AULA F75 has a larger 4000mAh battery compared to the Epomaker TH40's 3000mAh battery. While actual runtime depends on usage and RGB settings, the AULA F75's larger capacity suggests the potential for longer use between charges.

Yes, both keyboards use Cherry profile PBT keycaps and have standard mechanical switches, making them compatible with most aftermarket keycap sets. Note that the AULA F75 may have north or south-facing LEDs depending on the keycap version, which can interfere with the fit of certain sculpted keycap profiles.

Both keyboards have a 1000Hz polling rate in their wired and 2.4GHz wireless modes. The Epomaker TH40 product page specifically notes its Bluetooth polling rate is 125Hz.

The AULA F75 metadata lists silent linear switches, and its vendor page mentions options like the LEOBOG Reaper Switch. The Epomaker TH40 metadata lists linear switches, with its vendor page citing the EPOMAKER Flamingo Switch. Both are hot-swappable, allowing you to change them easily.

The AULA F75 is explicitly listed with silent switch options and features a more extensive five-layer sound-dampening design including two Poron foam layers, an IXPE pad, a PET pad, and silicone. The Epomaker TH40 also has foam layers but is not specifically marketed with silent switches, making the AULA the likely quieter option.

Yes, the AULA F75 has downloadable software, but the vendor description notes it only supports Windows. Some customer reviews reported issues with the software not detecting the keyboard, which is a potential drawback compared to the TH40's VIA support.

The AULA F75 includes the keyboard, a 2.4G dongle, a Type-C cable, a 2-in-1 keycap/switch puller, and a user manual. The Epomaker TH40 includes the keyboard, a USB cable, and a user manual.

Yes, but not as dedicated keys. Arrow functions are accessed via a function layer, meaning you hold a modifier key (like FN) and press other keys (often WASD or IJKL) to trigger arrow inputs. This requires memorization and is less immediate than dedicated arrows.

The AULA F75 lists a case material of plastic and aluminum, suggesting a potential metal top frame or weight for added rigidity. The Epomaker TH40 uses an ABS plastic case. The AULA F75 also features screw-in stabilizers, which are generally considered more stable and rattle-free than the TH40's plate-mounted stabilizers.
