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 Freedom 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
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.
