TWR-KW2xDxxx Development Platform Overview and Description
Tower KW2xDxxx Hardware Reference Manual, Rev. 0.2
2-2
Freescale Semiconductor
— Provides a Mini USB Type B coupled with OpenSDA used as debug interface, serial
communication and power supply (J13, Cortex 10-pin (0.05”) JTAG port for OpenSDA
updates)
— The TWR-KW24D512 also provides a Micro USB Type AB used as serial communication and
power supply.
Whether the TWR-KW2xDxxx is used in a simple standalone application or in combination with another
reference platform, Freescale provides a complete software development environment called the Freescale
BeeKit Wireless Connectivity Toolkit (BeeKit). BeeKit is a comprehensive codebase of wireless
networking libraries, application templates, and sample applications. A wide range of software
functionality are available to complement the TWR-KW2xDxxx platform and these are provided as
codebases within BeeKit.

Features
The TWR-KW2xDxxx development platform is built around Freescale’s concept of a standalone Tower
System Modular Development Platform that contains either the MKW21D256 device or the
MKW24D512 device and all necessary I/O connections for use as a self-contained board or for connection
to an application, but also has the capability to connect with the Tower System.
