The Rainy75 is a mechanical keyboard in a compact 75% layout with a standard profile and a gasket mount construction. It connects via Bluetooth 5, 2.4 GHz wireless, or USB, and runs at a 1000 Hz polling rate. The cable is detachable, and the board is not designed specifically for Mac. Physically, it measures 320 mm wide, 140 mm deep, and 40 mm thick, weighing in at 1800 g — a notably substantial weight for its size class.
The case is built from a combination of plastic and aluminum, with an FR4 plate underneath, and comes in six color options: black, white, blue, gray, pink, and silver. The keyboard features RGB backlighting and includes adjustable feet for typing angle customization. No wrist rest is included in the package.
The Rainy75 ships with Standard White HMX Violet Linear mechanical switches, which offer a smooth, linear feel with a 45 g actuation force and a total travel distance of 3.5 mm. The switches are hot-swappable, meaning they can be removed and replaced without soldering, giving users the flexibility to install different switches without specialized tools or permanent modifications.
On the software side, the Rainy75 supports both QMK and VIA, giving users access to deep key remapping and live configuration through widely used open-source tools. It does not support ZMK. The board lacks rapid trigger, dual actuation, and adjustable actuation point functionality, which places it outside the scope of keyboards targeting competitive gaming use cases that rely on those input precision features. There is also no USB passthrough or onboard display.
The Rainy75 uses an ANSI (United States) layout with a standard key arrangement, making it broadly compatible with off-the-shelf keycap sets. The included keycaps are double-shot PBT in an OEM profile, a construction method that keeps legends sharp and resistant to wear over time. Media functions are accessible via the Fn key rather than through dedicated keys, and the board does not include a rotary dial.
