EZR32 Happy Gecko 169 MHz Wireless Starter Kit


The Silicon Labs EZR32 Happy Gecko Wireless Starter Kit is an excellent starting point to evaluate and develop on the EZR32 Happy Gecko Wireless MCUs. The kit features an on-board J-Link debugger, an Advanced Energy Monitor for real-time current and voltage monitoring, a Virtual COM port interface, and access to the Packet Trace Interface (PTI).

The WSTK Mainboard is paired with an EZR32 Happy Gecko radio board that plugs directly into the mainboard. The radio board feature the EZR32 Happy Gecko device and the RF interface. All debug functionality, including AEM, VCOM and PTI, can also be used towards an external target instead of the included radio board. To further enhance the WSTK usability, the WSTK Mainboard contains sensors and peripherals demonstrating some of the Wireless MCU's many capabilities.
