Mechboards Keeb.io Iris

The Mechboards Iris is a split ergonomic keyboard kit designed for users who prioritize comfortable typing and customization. Its vertically staggered 4x6 key layout with up to 4 thumb keys reduces thumb stretching, which can improve typing efficiency and reduce strain. This keyboard suits hobbyists and enthusiasts comfortable with assembling or customizing their own keyboard, especially those who want a compact, ergonomic setup.

Key Features

• Split design separates hands to promote a natural wrist position and reduce fatigue during long typing sessions.
• Vertically staggered keys align with finger length, potentially improving typing accuracy and comfort.
• Up to 4 thumb keys allow for additional programmable inputs without stretching thumbs outward.
• Multiple kit versions available, including solder and solder-free hotswap options, catering to different skill levels and preferences.
• Supports MX mechanical switches, enabling users to choose switch type based on feel and sound preferences.

Build Quality

• Constructed with FR4 plates and PCBs, providing a sturdy and stable typing platform.
• Includes components such as SMD diodes, screws, standoffs, feet, and TRRS jacks for wired connectivity between halves.
• Case material and finish vary by kit version; some include a black FR4 case with underglow and per-key RGB lighting.

Typing Experience

• Split layout and thumb cluster reduce hand and thumb strain by minimizing reach.
• Hotswap versions allow easy switch replacement without soldering, facilitating experimentation with switch types.
• Rev 2 version supports only soldered through-hole LEDs, limiting lighting customization compared to later versions.

Connectivity

• Wired connection between keyboard halves via TRRS cable, ensuring reliable communication without wireless latency concerns.
• USB-C connector for host device connection, compatible with most modern computers.

Trade-offs

• Requires assembly and additional components such as switches, controllers, and USB cables, which may not suit users seeking a ready-to-use keyboard.
• Split ergonomic layout has a learning curve and may not be ideal for users accustomed to traditional keyboards.
• Limited lighting options on some versions, with soldered LEDs restricting easy customization.
