The NXP® MRB-KW0x is a modular reference board for MKW01Z128CHN platform, part of the Kinetis® W series of MCUs. Powered by the ultra-low-power 48 MHz Arm® Cortex®-M0+ 32-bit core, the Kinetis KW0x family of MCUs embeds a rich set of peripherals such as a high-performance, bi-directional sub-1 GHz radio capable of operating over a wide frequency range of 315, 433, 470, 868, 915, 928 and 960 MHz in the license-free industrial, scientific and medical frequency bands. There are three development tools available for the Kinetis KW0x platform, based on regional needs: * MRB-KW019032NA - 915 MHz with 32 MHz XTAL * MRB-KW019032EU - 868 MHz with 32 MHz XTAL * MRB-KW019030JA - 900 MHz with 30 MHz XTAL
