KBDFans Agar Mini vs zFrontier Zan 40: your questions
The KBDFans Agar Mini is easier for beginners. It is sold as a pre-built unit with keycaps, switches, and stabilizers already included, requiring minimal assembly. The zFrontier Zan 40 is a DIY kit that requires you to source and install your own switches and keycaps.
The zFrontier Zan 40 has an advantage in software due to its explicit support for VIAL. VIAL allows for real-time, graphical key remapping without needing to reflash the firmware. The Agar Mini uses a customized version of ZMK, which is powerful but may involve a different configuration process.
Yes, both keyboards offer wireless connectivity. The Agar Mini is a dual-mode (Bluetooth) kit powered by ZMK. The Zan 40 offers a 'Dual Mode' PCB option that includes a battery for Bluetooth and wired use.
The zFrontier Zan 40 features an isolated spacebar that supports a split layout. This means you can use two separate 3u keycaps in place of a standard 6u spacebar, programming each half as a different key or layer modifier for greater efficiency.
Yes, the KBDFans Agar Mini includes a 300mAh battery. The vendor claims that through optimization of the ZMK firmware, this battery can last up to three months on a single charge.
The KBDFans Agar Mini has stronger portability features. Its vendor specifically markets it for travel and includes a bespoke storage pouch for carrying. It also highlights an ultra-low front height designed for comfort without an external wrist rest.
Yes, both kits include screw-in stabilizers. The Agar Mini includes stabilizers with 3u wires for its unique layout. The Zan 40 includes stabilizers and wires for both a 6u spacebar and split 3u spacebars.
The Agar Mini uses a proprietary magnetic pogo-pin system to connect its daughterboard, which handles the USB port. This cable-free design, called a 'Serpentine Adaptive Connector,' is intended to eliminate issues with traditional ribbon cables wearing out over time.
Both keyboards offer color options, but at the point of purchase. The Agar Mini offers case colors like anodized black, gray, purple, silver, red, e-white, PC, and brass. The Zan 40 offers powder-coated colors like yellow, beige, light blue, lime, peach, and pink-lavender.
The KBDFans Agar Mini offers more plate material choices, including Polycarbonate, FR4, Aluminum, and Carbon Fiber. The zFrontier Zan 40 comes with an FR4 plate but offers numerous decorative backplate options, such as PVD stainless steel and titanium designs with various artworks.
Yes, the zFrontier Zan 40 PCB is listed as hot-swappable. This allows you to change MX-style mechanical switches without soldering, which is a key feature for customization.
