Bluetooth Low Energy/IEEEÂRegistered 802.15.4 Packet Sniffer USB Dongle based on kinetis ARM� Cortex�-M0+ KW40Z/30Z/20Z MCUs

Manufactured By:NXP
Part Number:USB-KW40Z

The USB-KW40Z is a development platform enabled by the Kinetis W series KW40Z/30Z/20Z (KW40Z) family built on the ARM® Cortex®-M0 processor in a convenient USB dongle form factor.  The USB-KW40Z can be used as a Bluetooth® Smart/Bluetooth® Low Energy and/or IEEE® 802.15.4 packet sniffer or development board. Packet sniffers are essential for wireless network development allowing over-the-air traffic monitoring.

The Kinetis KW40Z/30Z/20Z (KW40Z) wireless MCU family is the first multi-mode radio in the Kinetis portfolio. Integrating a Bluetooth® Low Energy (BLE) v4.1 and IEEE® 802.15.4- 2011 compliant modem, it can support both standards and run in concurrent mode.
