Cidoo ABM081 Stellar vs Royal Kludge RK84: your questions
The Royal Kludge RK84 has a larger 3750mAh battery compared to the Cidoo ABM081 Stellar's 3000mAh. The RK84 manufacturer claims it can last a week with the backlight off. Actual battery life will depend on usage patterns and lighting settings.
Yes, both keyboards support key remapping, but through different methods. The Cidoo ABM081 Stellar supports VIA, a popular and user-friendly web-based configurator. The RK84 uses its own proprietary software, which the vendor listing calls 'DIY Software Supports'.
The Royal Kludge RK84 is sold as a pre-built unit with ABS double-shot keycaps and your choice of RK switches (Red, Blue, Brown). The Cidoo ABM081 Stellar is available in both a pre-built version with MDA PBT keycaps and switches, and as a barebones kit without switches or keycaps.
The Cidoo ABM081 Stellar is likely better for a quiet office. Its design focuses on sound dampening with a gasket mount, polycarbonate plate, Poron foam, IXPE switch pads, and PET sheets to reduce typing noise. The RK84 does not list similar acoustic treatments.
The two USB 2.0 pass-through ports on the RK84 allow you to connect devices like a wireless mouse dongle or a USB headset directly to the keyboard. This can reduce cable clutter and make it easier to manage peripherals on a clean desk setup.
A gasket mount involves suspending the keyboard's plate and PCB between rubber or silicone gaskets within the case. This design, used by the Cidoo ABM081 Stellar, aims to reduce harsh vibrations and create a softer, more consistent typing feel with a potentially more pleasant sound signature.
According to its vendor page, the Cidoo ABM081 Stellar comes with pre-lubed, plate-mount stabilizers. The RK84 lists screw-in stabilizers but does not specify if they are pre-lubed from the factory.
Yes, both keyboards are compatible with Mac OS. The RK84 vendor description explicitly lists Mac OS support alongside Windows, iOS, and Android. The Cidoo ABM081's triple-mode connectivity and standard HID profile ensure it will also work with Mac systems.
The 1.14-inch TFT screen on the Cidoo ABM081 Stellar can display system information like time and date. More notably, the manufacturer states users can upload and showcase custom GIFs on the screen for personalization.
The Royal Kludge RK84 may have a slight portability edge. It has a specified weight of 803.5 grams and includes a short 5.6-inch cable. The Cidoo ABM081 Stellar's weight is not specified, and its cable length is not detailed, though both share the same 75% compact form factor.
The Royal Kludge RK84 vendor description mentions Bluetooth 5.0 for its wireless mode. The Cidoo ABM081 Stellar's specifications only state 'Bluetooth' without specifying a version, so its Bluetooth version cannot be confirmed from the provided information.
