FRDM Development Boards for Kinetis KW21Z, KW31Z and KW41Z MCUs. 2 boards per order

Note: K32W061/41 is preferred for

any new Zigbee®, Thread and Bluetooth® LE 5.0 design. No new software releases planned

The FRDM-KW41Z is a development kit enabled by the Kinetis® W series KW41Z/31Z/21Z (KW41Z) family

built on Arm® Cortex®-M0+ processor with integrated 2.4 GHz transceiver supporting

Bluetooth® Smart/Bluetooth®Low Energy (BLE) v4.2, Generic FSK, IEEE®

802.15.4 and Thread. The FRDM-KW41Z kit contains two FRDM boards that can be used as a development board or a shield to connect to a

host processor. The FRDM-KW41Z is form-factor compatible with the Arduino® Rev3 pin layout for more

expansion options. The FRDM-KW41Z highly-sensitive, optimized 2.4 GHz radio features a PCB F-antenna which can be bypassed to test via

SMA connection, multiple power supply options, push/capacitive touch buttons, switches, LEDs and integrated sensors.

The FRDM-KW41Z platform is now supported by Arm® Mbed™ OS and Zephyr®OS, both open source embedded operating systems for

developing the Internet of Things.
