The Wireless Gecko SLWRB4180A wireless radio board plugs into the Main Board provided with the Wireless Gecko Starter Kit. The starter kit includes access to Zigbee and Thread software stacks. The modular design supports different radio boards, enabling developers to develop Zigbee, Thread and proprietary wireless applications. With the supporting Simplicity Studio suite of tools, developers can take advantage of graphical wireless application development; mesh networking debug and packet trace; and visual energy profiling and optimization.
