Hi75C Series Mechanical Keyboard

Less Bulk. More Control. All You Need.

Amastris Tech designed the Hi75C for the kind of person who doesn't want to choose between a clean desk and a capable keyboard. The compact 75% layout fits 81 keys into a footprint that leaves you room to breathe — without dropping a single key you actually use. Whether you're mid-session or on the move, it keeps up without getting in the way.

Built Around How You Type

Hot swappable mechanical switches mean your keyboard evolves with you. Swap out switches in seconds — no soldering, no technical headaches — until the feel is exactly right. Tactile, linear, clicky: the choice is yours, and it's always reversible. Full RGB backlighting adds personality and keeps every key visible when the lights go down, while PBT double shot keycaps ensure the legends stay sharp no matter how many hours you put in.

• 81-Key 75% Layout — compact without sacrificing functionality
• Hot Swappable Switches — tool-free, solder-free customization
• Full RGB Backlighting — per-key lighting with full personalization
• PBT Double Shot Keycaps — premium feel, built to last

One Keyboard, Every Setup

Bluetooth, 2.4GHz wireless, and USB wired connectivity give you seamless switching across Windows, macOS, Linux, and Android. A 4,000mAh battery keeps you untethered for the long haul, and the aluminum chassis with advanced gasket mounting delivers a typing experience that feels as premium as it looks.

Amastris Tech builds keyboards for people who notice the difference. The Hi75C is compact by design, capable by nature — and refined enough to belong on any desk.
