Keychron C3 Pro vs Lemokey L3: your questions
No, the Keychron C3 Pro is a wired-only keyboard. It connects via a Type-A to Type-C cable and does not support Bluetooth or 2.4 GHz wireless connections. For wireless use, you would need to look at a model like the Lemokey L3.
Yes, the Lemokey L3 fully supports macOS, Windows, and Linux. It comes with extra keycaps for Mac users, and the QMK/VIA software allows you to remap keys for any operating system. You can switch between up to 3 Bluetooth devices.
Yes, both the Keychron C3 Pro and the Lemokey L3 feature hot-swappable PCBs. This means you can change switches without soldering, and they are compatible with most 3-pin and 5-pin MX-style switches from brands like Cherry, Gateron, and Kailh.
The Keychron C3 Pro has north-facing red LED backlight with shine-through ABS keycaps, making the legends more visible in the dark. The Lemokey L3 has south-facing RGB with 22 backlight modes but uses non-shine-through PBT keycaps, so the lighting is more ambient.
The Lemokey L3 justifies its higher price with a full CNC machined aluminum body, dual wireless connectivity, a 4000mAh battery, screw-in stabilizers, and a rotary knob. If these premium features and build quality matter to you, it is a worthwhile investment over the plastic C3 Pro.
Yes, both keyboards support full QMK and VIA software, which allows you to remap any key and create custom macros. The C3 Pro requires a JSON file to be loaded into VIA, while the L3 also supports the Lemokey Launcher web app for easier configuration.
The Keychron C3 Pro weighs about 912 grams, making it much more portable. The Lemokey L3 weighs approximately 1976 grams due to its full aluminum case, which is over twice as heavy and better suited for a permanent desk setup.
It depends on the version. The 'Fully Assembled' version includes Cherry profile double-shot PBT keycaps and Gateron Jupiter switches. The 'Barebone' version does not include keycaps or switches, allowing you to source your own.
The Keychron C3 Pro has a maximum polling rate of 1000 Hz when used in its default mode. The vendor also lists an 8000 Hz option, but the product description specifies 1000 Hz right out of the box for competitive gaming.
The Lemokey L3 is better for modding due to its screw-in stabilizers, aluminum case, and PC plate, which provide a superior foundation for sound and feel tuning. It also offers a barebone kit option for complete component selection. The C3 Pro is more limited with plate-mounted stabs and a steel plate.
The product specifications for the Lemokey L3 do not mention adjustable typing feet. The Keychron C3 Pro offers three levels of adjustment (4, 6, and 8.7 degrees), which may be important for ergonomic comfort.
The Lemokey L3 is equipped with a 4000 mAh rechargeable lithium-polymer battery. According to the vendor, it can last up to 200 hours with backlighting off or up to 100 hours with RGB at the lowest brightness.
