About the Keychron B1 Pro Ultra-Slim Wireless Keyboard (Retro Blue)
The Keychron B1 Pro is a slim 75% wireless keyboard with scissor-switch keys and a 77-key layout that keeps the function row and arrow keys in a small footprint. It suits students, remote workers and travellers. This B1P-K11 version uses Keychron’s retro blue colourway, which adds colour to an otherwise plain office keyboard. It connects over 2.4 GHz, Bluetooth 5.2 to three devices, or a USB-C cable, and works with macOS, iOS, Windows, Android and Linux. Keys can be remapped in the Keychron Launcher web app.
