All the features of a custom build. Priced like a daily driver. The RO75 packs high-end materials, gasket mounting, and tri-mode wireless into a compact 81-key layout. It’s hot-swappable, dead quiet, and comfortable to type on all day. With wired, Bluetooth, and 2.4G options, it fits seamlessly into any workflow. CNC-milled aluminum case The RO75’s top and bottom cases are CNC-milled from 6063 aluminum alloy, sandblasted to a 220-grit finish, and either anodized, powder coated, or UV-treated depending on your selected colorway. A 304 stainless steel mirror-polished weight gives it 3.7lbs of heft while the finish feels cool and smooth to the touch. Quick detachable ball structure You can keep your toolbox in the garage for this one. Thanks to four sets of custom steel ball locks, the RO75’s top case just pops off. Want to swap switches, mod foam, or change your keycaps? Just pop, lift, and go. Gasket-mounted and foam-packed Typing on the RO75 feels clean, quiet, and soft thanks to a full-stack gasket mount system and a five-layer sound-dampening sandwich. There’s PORON foam, IXPE switch pads, PET acoustic sheets, and EPDM underfill all working together to tame pinginess and deepen the sound. PBT + ABS dye-sub keycaps The keycaps are Cherry profile with thermal sublimation legends on the PBT tops and translucent ABS sides that allow RGB lighting to shine through. Upgraded IC RGB lighting Unlike traditional RGB setups that use separate R/G/B chips and daisy-chained wiring, the RO75 uses integrated IC RGB LEDs. Each LED includes its own driver chip, which means smoother transitions, simplified wiring, and more precise control over lighting effects—especially through VIA or VIAL. Tri-mode connectivity With three ways to connect, you have more control over your workflow. USB-C wired for zero-latency performance 2.4G wireless for stability and range Bluetooth for quick toggling between up to three paired devices VIA and VIAL compatible Prefer to tweak your layout, lighting, or macros? The RO75 supports both VIA and VIAL. Download the matching JSON file, load it into the software, and start customizing. Choose your switches: linear or tactile Pink Robin (Linear): POM stem, PBT top and bottom, 48g actuation, 3.5mm travel. Clean, consistent, and great for fast typists. Fantasy Dream (Tactile): POM stem, ABS top, PBT bottom, 67g actuation, 3.2mm travel. Higher tactility with a crisp bump.
