What will you mostly use it for?
The Keychron K3 V3 wins for programming and content creation due to its more functional layout and superior QMK programmability. It also has an edge for gaming and modding. The MelGeek Mojo68 is the more portable choice for travel due to its smaller size, despite its heavier weight, and ties for office use thanks to its long battery life. The decision is largely defined by the need for a low-profile, programmable board versus a standard-profile, highly portable one with a 2.4 GHz option.
Pick the Keychron K3 V3
- The K3 V3 has a 1000 Hz polling rate in wired mode, which the manufacturer states makes latency hardly noticeable.
- Its low-profile design and adjustable typing angles may offer a faster, flatter keypress feel preferred by some gamers.
- The Mojo68 also has a 1000 Hz polling rate, but its heavier weight makes it less convenient for quick repositioning.

Keychron K3 V3 vs MelGeek Mojo68: your questions
The MelGeek Mojo68 may have an edge for wireless gaming as it maintains a 1000 Hz polling rate over its 2.4 GHz connection, according to its product listing. The Keychron K3 V3's wireless polling rate is 90 Hz over Bluetooth, though it offers 1000 Hz in wired mode.
No. The Keychron K3 V3 is designed for low-profile switches only. The manufacturer states it is compatible with Keychron Milk POM switches or Gateron/Keychron low-profile mechanical switches. Standard Cherry MX switches will not fit.
Yes. The vendor specifications for the MelGeek Mojo68 list compatibility with Windows, Mac, and Linux operating systems.
The MelGeek Mojo68 has a significantly larger 4000mAh battery compared to the Keychron K3 V3's 1550mAh battery. This suggests the Mojo68 will last longer between charges during wireless use.
Yes, but only through the proprietary MelGeek KBTools app. The Mojo68 does not support the open-source QMK or VIA firmware that the Keychron K3 V3 uses for customization.
The K3 V3 is lightweight at 540g, which is good for travel. However, its 75% layout is slightly larger than the Mojo68's 65% layout. Its low-profile design also makes it slimmer, which can be an advantage for packing.
Both keyboards feature sound-dampening materials. The K3 V3 uses IXPE, EPDM, and latex foam, while the Mojo68 uses a Poron switch mat, Poron foam, and a silicone pad. The K3 V3's low-profile switches may also contribute to a quieter acoustic profile, but the actual sound will depend on the specific switch type installed.
The product description does not mention a wrist rest being included. It does feature three adjustable typing angles (2.5°, 4.2°, and 6.5°) for ergonomic support.
The Keychron K3 V3 uses a 75% layout with 84 keys, retaining the function row, navigation cluster, and 12 multimedia keys. The MelGeek Mojo68 is a 65% layout with 68 keys, which removes the function row and dedicated navigation keys, relying on layers for those functions.
Yes, both have RGB backlighting with shine-through keycaps. The K3 V3 uses LSA profile ABS keycaps with north-facing LEDs, while the Mojo68 uses south-facing RGB LEDs with its keycaps.
The Keychron K3 V3's description mentions 22+ dynamic RGB backlight settings with adjustable hue, saturation, brightness, and effect speed. The MelGeek Mojo68's listing confirms RGB lighting but does not specify the number of effects or customization depth.
