NXP wireless solutions build upon decades of Wi-Fi and Bluetooth silicon, system and software design expertise. NXP is committed to drive large-scale deployment across multiple markets by a broad array of power- and cost-optimized Wi-Fi and Bluetooth chipsets, enabling products with today’s most advanced Wi-Fi capabilities.

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 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.
