Roll over image to zoom in

The USB-KW41Z is a development platform enabled by the Kinetis® W series KW41Z/31Z/21Z (KW41Z) family built on the Arm® Cortex®-M0+ processor in a convenient USB dongle form factor.

The USB-KW41Z can be used as a Bluetooth® Smart/Bluetooth® Low Energy and/or IEEE® 802.15.4 packet sniffer or development board.

The USB Dongle used as a wireless packet sniffer can monitor over-the-air communications. Alternatively the USB dongle can be used as a wireless network node with a simple connection to a PC or other USB enabled device.

Note: K32W061/41 is preferred for any new Zigbee®, Thread and Bluetooth® LE 5.0 design. No new software releases planned
