Agar mini

The Agar Mini represents the latest evolution in the esteemed Agar series, distilling its signature design language into a new compact form factor.

This model preserves the elegant, curved aesthetic iconic to the lineage, while further streamlining the layout to create a highly portable and efficient input device.

Appearance

Classic Design, Unmatched Portability
The Agar Mini translates the iconic Agar design language into a more refined and compact form factor, retaining its signature gentle curves while introducing a delightful new aesthetic. A key feature is its ultra-low front height, which is engineered for superior ergonomic comfort, allowing for extended typing sessions without the need for a wrist rest.
For ultimate convenience, the Agar Mini comes complete with a bespoke storage pouch. This makes it easy to pack and carry, establishing it as the perfect companion for use at home, in the office, and on the go.

Ergonomic Angle and Premium Weight System

The Agar Mini is designed with a fixed 9-degree typing angle for ergonomic comfort and an assertive profile.

The bottom case is equipped with an interchangeable accent weight system for customization. This allows users to alter the keyboard's visual hierarchy with different materials and finishes.

The Art of the Curve: Sculpting a New Form

The Agar Mini challenges the conventional perception of a metal keyboard. Sharp angles do not define its side profile, but by a dynamic interplay of fluid lines reminiscent of a dancer in motion. The result is a design that feels both understated and confidently present.

This sculptural form is achieved through the use of complex, compound curves—a deliberate choice that, while demanding in its manufacturing, is essential to achieving the sophisticated aesthetic we envisioned. For us, this pursuit of an elevated finish is non-negotiable.

Front Profile: Gentle by Design

The front profile highlights the Agar series' signature design cue: soft, inwardly tapering side curves that create a lighter, more gentle visual impression.

Departing from a conventional linear edge, the front lip is defined by a smooth, organic curve. This detail reinforces the keyboard's overall gentle aesthetic, resulting in a design that is both visually pleasing and inherently inviting to the hand.

PCB Gasket Mount

A Revolution in Assembly: The Proprietary Mounting System

The Agar Mini utilizes the same mounting structure as the Agar, designed to replace conventional O-ring systems. This design eliminates the need for specific gasket ring sizes, clip-in stabilizers, and complex foam configurations.

The core of the system is a bespoke set of structural silicone components, precision-molded to a 50A durometer hardness. This allows the core assembly to be installed or removed in approximately two seconds, offering an unparalleled level of efficiency without compromising on a premium typing experience.

Three PCBs available

The Agar Mini is available in three distinct versions to cater to different user preferences:

Wired Edition: Powered by QMK firmware, this version offers comprehensive programmability and is fully compatible with VIA, VIAL, and AVA real-time configuration tools.

Dual-Mode Wireless Edition: Built on ZMK firmware, this version features ultra-low-power Bluetooth connectivity for a stable and long-lasting wireless experience. It is fully customizable via the zmk.studio editor.

EC Edition: Powered by QMK firmware, this version offers comprehensive programmability and is fully compatible with VIAL real-time configuration tools.

Whether you are a minimalist pursuing ultimate portability or a customization enthusiast who demands complete functional freedom, the Agar Mini stands as an ideal input device that masterfully balances aesthetic elegance with practical functionality.

Innovative Daughterboard Connection: 

We are introducing our proprietary "Serpentine Adaptive Connector" for the daughterboard. This unique, cable-free system utilizes a magnetic pogo-pin connection, eliminating the need for traditional ribbon cables. This elegant solution drastically reduces potential long-term issues caused by cable wear and tear, ensuring superior reliability.

The Wireless Experience, Perfected: More Stable, Lasts Longer

The Agar Mini marks KBDfans' debut into dual-mode wireless kits powered by ZMK firmware. Setting it apart from conventional solutions on the market, ZMK delivers an exceptionally stable Bluetooth experience, distinguished by its modular architecture and ultra-low power consumption.

Thanks to our meticulous tuning and optimization, the Agar Mini achieves a remarkable battery life of up to 3 months, even with just a 300mAh battery. We didn't stop there; we've further enhanced the native ZMK functionality with several key improvements:

  • Full Indicator Light Support: We've custom-implemented indicator functionality, a feature not natively available in ZMK.
  • Optimized Connectivity: Bluetooth connection speed and stability have been significantly improved.
  • Future-Ready: Seamless integration with the AVA configurator is planned, ensuring an even smoother user experience down the road.

Layout

Click here about Key Function Manual

The Agar Mini is built upon a custom 40% layout with a total width of 13 units (13U).

In contrast to more common 12U compact designs, this 13U width offers superior visual and proportional balance.
It elegantly avoids the cramped profile that can result from a 0.5U reduction on the modifiers,
lending the entire chassis a more harmonious and fluid appearance.

In its layout philosophy, the Agar Mini pays homage to the classic HHKB style while utilizing a standard staggered key arrangement.

This thoughtful combination ensures a familiar typing experience, minimizing the learning curve and
making it immediately accessible to a wide range of users.

FAQs

Q: Is the Agar Mini fully programmable and what firmware does it use?

A: Yes, it is fully programmable.

  • Wired: QMK firmware (supports VIA, VIAL, AVA).
  • Dual-Mode: ZMK firmware (supports zmk.studio, with future AVA support planned). It's designed to be intuitive for all skill levels.

Q: How long does the wireless Agar Mini's battery last?

A: The dual-mode model includes an 800mAh battery. Thanks to the power-efficient ZMK firmware, you can expect around 2-3 months of battery life with normal use. This can fluctuate based on your personal usage patterns.

Q: Is the Agar Mini hot-swappable? Does it support EC switches?

A: Yes.

Hot-swap: Both the wired and dual-mode PCBs are hot-swappable and support most MX-style switches.

EC Switches: An EC-compatible PCB is planned for the future. Stay tuned to KBDfans for updates.

Q: What wireless protocols does the dual-mode version use? Is the connection stable?

A: It uses ZMK firmware with Bluetooth 5.0 for a highly stable connection. We've also optimized the base ZMK firmware with improvements to the connection process, indicator light support, and power efficiency. It is compatible with most major operating systems (Windows, macOS, Linux, Android, iOS).

Q: How is its structure and feel different from an O-ring keyboard?

A: It uses a custom, one-piece silicone mounting system (50A hardness). This is superior to traditional O-rings because:

Installation is simpler: It's a 2-second, snap-in process.

It's more compatible: No need to worry about specific stabilizer sizes.

The typing experience is better: The feel is more stable and the sound is deeper.

Q: What stabilizers does it support?

A: No special selection is needed. It is compatible with most mainstream MX-style stabilizers, including both screw-in and clip-in types, making installation easy. And the stabilizers are included in this kit.

Q: Is a wired-only version available?

A: Yes. You can choose between:

Wired Version: Best for fixed desktop use.

Dual-Mode Version: Best for portable/mobile use.

Q: Does the case scratch easily? Is the finish under warranty?

A: The case has a high-quality finish (anodizing, e-coating, etc.), but this finish is not covered by the warranty. Normal wear, like minor scuffs, patina, or smudges from regular use, is to be expected. We advise using a keyboard case and routine cleaning to maintain its appearance.

Q: How do I flash firmware or a new keymap?

A: The method depends on your version:

Wired: Flash via VIA, VIAL, or QMK Toolbox.

Dual-Mode: Generate your firmware on zmk.studio and flash the file in bootloader mode.

We provide detailed guides and videos for both processes.

Q: Can the Agar Mini use AVA?

A: Yes. The Wired version is compatible now, and support for the Dual-Mode version is coming soon, making it even easier to use in the future.
