Description

Compact without losing the keys you need

The 75% layout keeps the F-row and the arrow keys but drops the number pad, so the mouse sits closer to your hand. Damping foam and a steel plate give a stable, quiet keypress. OSA profile double-shot PBT keycaps hold up to long use, and keys and macros are set up with QMK firmware and the Keychron Launcher web app.

Who this keyboard is for

Anyone who wants one keyboard for both a PC and a Mac: according to Keychron, keycaps for both systems are in the box and a system toggle sits on the case. Hot-swap sockets suit anyone who wants to try other switches later. If you enter a lot of numbers, a full-size model will serve you better.

Questions & answers

Does the keyboard have Estonian letters?

No. The layout is English ENG (ANSI), so Õ, Ä, Ö and Ü are not printed on the keys. To type in Estonian, add the Estonian keyboard layout in your system settings.

What is the difference between K2M-J3 and K2M-J1?

Connections, battery, layout and key count are the same on both. The manufacturer does not specify the switch type (linear or tactile) for either version, and the case material listed for the K2M-J3 is ABS.

How many devices can it pair with?

According to Keychron, up to three over Bluetooth, plus the 2.4 GHz receiver and a USB-C cable. The 4000 mAh battery is rated at up to 190 hours.
