Epomaker TH40 vs TH87Ultra-Compact 40% vs TKL Layout Choice

The core difference is layout. The TH40 is a 40% keyboard with only 44 keys, requiring heavy use of function layers. The TH87 is an 87-key tenkeyless (TKL) keyboard with a standard layout that includes arrow keys, function row, and navigation cluster. This fundamental difference drives all other comparisons regarding portability, learning curve, and intended use case.

The Epomaker TH87 has a significantly larger 10000mAh battery. According to its specifications, it offers up to 45 hours of continuous use with RGB lighting at its brightest, or an estimated 200 hours with lighting off. The TH40 has a 3000mAh battery, which is smaller but appropriate for its more compact size and lower power draw from fewer LEDs.

Yes, but the method and depth differ. The TH40 supports VIA and QMK, which are open-source, cross-platform solutions for extensive remapping and macro creation on multiple programmable layers. The TH87 uses proprietary programming software which, according to its vendor page, is for Windows only. The TH40 offers more flexible and accessible software customization.

The Epomaker TH40 is far more portable. It measures 258 x 97 x 35 mm and weighs 500g, designed as an ultra-compact board. The TH87 measures 367 x 142 x 41 mm and weighs 1000g. The TH40's 40% layout is explicitly marketed for those on the move and will fit easily into a bag.

Only the Epomaker TH87 is listed with an explicit silent switch option, the Sea Salt Silent Switch. The TH40's metadata and vendor description only mention linear switches. If quiet typing in an office is a priority, the TH87 with silent switches is the clear choice.

Yes, both keyboards feature hot-swappable PCBs. The TH40 supports 3-pin and 5-pin switches. The TH87 also supports 5-pin switches. This allows you to easily change the mechanical switches without soldering on either model.

Both use gasket mounts and internal foam. The TH40 uses Poron plate foam, an IXPE switch pad, and bottom Poron foam. The TH87 features a more detailed 5-layer system with PORON sandwich foam, IXPE switch pad, sound enhancement pad, EPDM switch socket pad, and a silicone bottom. The TH87's design is more explicitly focused on sound optimization.

The Epomaker TH87 is better for beginners. Its standard TKL layout requires no retraining, and it includes helpful features like an adjustable kickstand and a silent switch option. The TH40's 40% layout has a steep learning curve and is better suited for enthusiasts seeking a specific compact form factor or deep programmability.

According to its vendor page, the TH87 includes the keyboard, a USB A-to-C cable, a 2.4Ghz receiver (stored under the kickstand), two extra switches, a 2-in-1 switch and keycap puller, and a manual. The TH40's listing shows it comes with just the keyboard, a USB cable, and a user manual.

The Epomaker TH87 includes a two-stage kickstand that offers three adjustable typing angles: 6 degrees, 8 degrees, and 10.5 degrees. The TH40 does not have an adjustable typing angle or kickstand mentioned in its specifications.

Both keyboards list Mac compatibility in their metadata. However, user reviews for the TH40 indicate some users experienced difficulties getting the VIA configuration software to recognize the keyboard on macOS. The TH87's proprietary software is listed as for Windows only, though the keyboard's basic functions will work on Mac.
