USB-KW40Z development board
4.1
USB-KW40Z board overview
The USB-KW40Z board is an evaluation board based on the Freescale MKW40Z160 SoC. The
USB-KW40Z provides a platform to evaluate the MKW40Z160 SoC device and to develop software and
applications. The core device is accompanied by a the 32 MHz reference oscillator crystal, RF circuitry
including antenna, and supporting circuitry.
The USB-KW40Z board is intended as the core PCB for MKW40Z160 device evaluation and application
development, and can be used as a simple standalone valuation solution or as packet sniffer.
