Cidoo ABM084 Mechanical Keyboard

The Cidoo ABM084 is a compact 84-key mechanical keyboard suited for users who want versatile connectivity and hot-swappable switch options. It fits well for hobbyists who like customizing switches and keycaps, and for users needing wireless or wired modes with programmable macros. Its design balances portability with solid build features and moderate typing noise reduction.

Key Features

• Hot-swappable TTC sockets support both 3-pin and 5-pin switches, allowing easy switch replacement without soldering.
• Triple connectivity modes include Bluetooth 5.0, 2.4GHz wireless, and wired USB Type-C, offering flexibility for different devices and use cases.
• Aluminum control knob offers volume and media control by default, with a secondary mode for adjusting backlight and brightness.
• RGB backlighting with 16.8 million colors and compatible software enables customizable lighting effects.
• Large 3000mAh battery supports extended wireless use, with up to 26 hours on Bluetooth with lighting on.

Build Quality

• Case made of nylon with a POM core provides a balance of durability and light weight (about 1012g).
• Poron foam layers between the plate and PCB, and at the bottom case, reduce hollow sounds and soften typing feel.
• PBT dye-sub keycaps in KDA or Cherry profile resist wear and maintain color over time.
• Stabilizers come factory pre-lubed for smoother keypresses.

Typing Experience

• Linear TTC switches with 49gf operating force offer a smooth, consistent keystroke suited for both typing and gaming.
• Poron foam layers improve acoustics by absorbing sound and vibration, resulting in a quieter, more solid typing feel.
• Hot-swap sockets allow users to try different switch types without soldering, enhancing customization.

Connectivity

• Bluetooth 5.0 mode supports mobile and desktop devices with moderate latency and up to 26 hours battery life with lighting on.
• 2.4GHz wireless mode offers a higher polling rate (up to 1000Hz), better for gaming responsiveness.
• Wired USB-C mode enables macro programming and eliminates wireless latency.
• Switching between modes is done via keyboard shortcuts for convenience.

Compatibility

• Supports Windows, MacOS, and Android systems, covering most common platforms.
• Software allows customization of lighting and macros, though firmware details are unknown.

Trade-offs

• At about 1012g, it is not the lightest 84-key keyboard, which may affect portability.
• Linear switches may not suit users who prefer tactile or clicky feedback.
• Battery life varies significantly between wireless modes and lighting usage, which may require frequent charging under heavy use.
• Unknown firmware update support could limit long-term customization or fixes.
