Keychron K5M-H3 Wireless Mechanical Keyboard

Keychron K5M-H3 Wireless Mechanical Keyboard

The Keychron K5M-H3 is a full-featured, low-profile mechanical keyboard with 108 keys and support for 2.4GHz wireless, Bluetooth 5.1 and wired connectivity via USB-C. It features a low-profile design based on an aluminum-plastic chassis, support for QMK/VIA, programmability of each key, NKRO support, RGB backlighting and long runtime. It is possible to replace the switches without soldering. The device is compatible with macOS, Windows and Linux, and comes with overlays and additional keycaps for easy switching between systems.

Lower profile, greater comfort

The use of Gateron Low-Profile 2.0 switches with a height of just 12.2 mm has created one of the thinnest mechanical wireless keyboards on the market. The overall height with overlays is only 23.5 mm at the back and 18.2 mm at the front, reducing the need for a wrist rest and increasing comfort while typing. In addition, three levels of keyboard angle (3.37°, 4.36° and 6.56°) allow you to adjust the keyboard to your preference.

Interference-free operation

The Keychron K5M-H3 Wireless Mechanical Keyboard offers three connection modes - 2.4 GHz with a 1000 Hz readout frequency, Bluetooth 5.1 with support for three devices, and wired via USB-C. As a result, you can switch seamlessly between computer, tablet and phone without re-pairing. The device supports full N-Key Rollover regardless of mode, eliminating the problem of missed presses.

Full freedom of settings

Compatibility with open QMK/VIA software allows full customization of the keyboard's functions - from assigning macros to changing the layout. Built-in memory based on the ARM STM32F402 microcontroller with 256KB of Flash memory allows settings to be saved locally. Configuration can be done through a browser in the Keychron Launcher application without installing additional software.

Flexible switch replacement

The Keychron K5M-H3 mechanical keyboard allows quick and secure switch replacement without soldering. Thanks to its compatibility with Gateron/Keychronm mechanical low-profile switches, you can easily adjust the characteristics of the keys to your preference - from quiet and smooth to more tactile and springy. The hot-swap socket mechanism eliminates the risk of damaging the motherboard, and changing switches takes just a moment. Note: the keyboard does not support optical switches.

Write quieter, work longer

IXPE acoustic foam is used inside the case to improve the acoustic experience, reduce typing noise and increase switch stability. Improved stabilizers ensure even operation of larger keys, such as space bar and Enter. The overlays are made of abrasion-resistant PBT plastic with double-shot technology, which increases durability and eliminates shine even with heavy use.

Striking backlighting

Enjoy more than 22 RGB backlighting modes that can be fine-tuned - from hue to brightness to speed of effects.
