Compact 75% Layout

The costom M87 Pro is a 75 per cent mechanical gaming keyboard with 87 keys and a tactile switch feel. It connects through USB-C wired, Bluetooth 5.1 or 2.4 GHz wireless modes. An integrated OLED colour display and a mechanical knob show status and control volume, lighting and connection changes.

Tri-Mode Build Flexibility

Switch between wired USB-C, Bluetooth 5.1 and 2.4 GHz wireless by turning the knob or using key combinations. The hot-swappable PCB accepts most three-pin and five-pin switches without soldering. Three internal dampening layers plus space-bar foam reduce vibration and sharpen key sound. A 3000 mAh battery supports up to seven days of typical eight-hour daily use.

For Customisation-Focused Users

Suits builders who want a compact layout with extensive per-key RGB, macro programming and on-board OLED personalisation through the driver software. Not suited for users who require a full-size numpad, dedicated media keys or a lower-profile typing experience.

Questions about this item

How long does the 3000 mAh battery last before I have to recharge it?

The built-in 3000 mAh battery delivers up to 7 days of typical use at 8 hours per day.

Does the OLED knob or the triple-layer dampening make the keyboard louder during all-day sessions?

The triple absorption layers — EVA foam, IXPE switch pad and sponge case foam — plus space-bar silencer foam reduce vibration and lower key noise for extended typing.

What do I need to plug in before the 2.4 GHz wireless mode works?

Insert the supplied 2.4 GHz USB dongle into a USB port on the computer, then select 2.4G via the knob.
