An ultra-low-power ARM Cortex-M4 32-bit STM32L432 MCU which is powerful, and equipped with 128K Flash will provide more flexibility for developers.

Wireless and Wired

Connect the K4 Pro with up to 3 devices wirelessly via its stable Broadcom Bluetooth 5.1 for seamless multitasking whether on Mac, Windows or Linux. Switch among them swiftly. The polling rate is 1000 Hz on USB Type-C wired mode (90 Hz on wireless mode).

Hot-swappable
