MIIIW Xiaomi Z830 vs Xiaomi ART Z870Hot-Swap 75% vs Aluminum TKL Keyboard

The product specifications and vendor description for the MIIIW Z870 do not mention hot-swap capability. It is listed as a pre-built keyboard. In contrast, the Z830 is explicitly described as hot-swappable for 3-pin and 5-pin switches.

Both keyboards list Mac support. The Z870's vendor description specifically highlights a "Design For Mac" with quick operation keys matching the original factory layout and includes Mac keycaps for replacement. The Z830 also supports Mac but its description focuses more on Windows software features.

According to vendor listings, the Z830 comes with Gateron G-Pro Yellow linear switches. The Z870 comes with Kailh BOX Red linear switches. Both are linear switch types, but with different actuation forces and travel distances as specified by their manufacturers.

Both keyboards house a 4000mAh lithium polymer battery. The Z830's vendor claims a battery life of over 200 days on a single charge. The Z870's listing does not provide a specific duration estimate, but both share the same battery capacity and charging time of about 3 hours.

Yes, both support triple-mode connectivity via wired USB-C, 2.4GHz wireless, and Bluetooth. The Z870's description states its Bluetooth supports connections with up to 5 devices simultaneously. The Z830's description confirms multi-device connectivity but does not specify a Bluetooth device limit.

The Z830 uses a 75% layout (83 keys) which condenses the function row and navigation cluster into a compact block, often requiring a function layer for some keys. The Z870 is a TKL or 80% layout (87 keys) which removes the number pad but retains the function row, arrow keys, and a dedicated navigation cluster separately.

A gasket mount is a design where the keyboard's internal plate is suspended on rubber or silicone gaskets to reduce harsh vibrations and create a softer typing feel.
