Outdated Product
A super-compact ultra-light wireless mouse featuring revolutionary small dimensions (only 8.6 cm in length — half the size of a standard model), weighing just 35 g, with three connectivity options (radio channel, Bluetooth 5.1, cable), long-lasting Huano switches, and a Keychron Launcher web configurator for setup without installing software. Released in 2024 specifically for highly mobile users who need a portable tool for working with tablets, ultrabooks, or in extremely constrained spaces. Its extremely small size allows it to easily fit even in a clothing pocket, and the minimal weight of 35 g makes it nearly weightless during transport and provides full fingertip control. The Keychron M4 4000 Hz wireless mouse is equipped with a PixArt 3395 sensor with a resolution range from 1...00 to 26000 DPI, maintaining tracking accuracy at accelerations up to 50G and movement speeds up to 650 IPS. The polling rate reaches 4000 Hz in 2.4 GHz and wired connection modes, providing a response time of 0.25 ms. External buttons allow for adjusting resolution and polling rate directly on the device. The web configurator works through a browser and supports five memory profiles. Huano switches are rated for 80 million clicks. A 300 mAh battery provides up to 67 hours of autonomous operation.
