EPOMAKER has released the RT75, a compact mechanical keyboard that lets buyers choose between a small display or extra keys in the top-right corner. This modular design matters because it lets users customize the layout for specific workflows without buying a new device. The keyboard ships now in China for around $89 to $90.
Modular design allows users to swap a small TFT screen for four extra keys
The RT75 uses a 75% or 80% layout with 83 or 87 keys. It connects via tri-mode wireless, wired, or Bluetooth. The body combines an ABS plastic shell with an aluminum middle frame. A gasket mount structure is used to reduce vibration.

EPOMAKER offers two switch options for the RT75. The Cloud Jade switches provide a HiFi sound profile. The Crystal Silent Tactile switches offer a quieter typing experience.

The keycaps are made of PBT material with a Cherry profile. They use dye-sublimated printing for durability. The top-right corner supports a 1.54-inch detachable TFT screen. Users can replace the screen with four standard keys if they prefer. We looked at EPOMAKER RT100 PRO Tri-Mode Keyboard Launches in our earlier Epomaker coverage.
