Silicon Labs Flex Gecko EFR32 Wireless Protocol Development Starter Kit SLWSTK6061A

The SLWSTK6061A Wireless Starter Kit (WSTK) is an excellent starting point to get familiar with the EFR32 Flex Gecko Wireless System-on-Chip (SoC). The WSTK BRD4001A mainboard features an on-board J-Link debugger, an Advanced Energy Monitor (AEM) for real-time current and voltage monitoring, and a Virtual COM port interface (VCOM). Packet Trace Interface (PTI) is supported.
The mainboard (BRD4001A) is paired with the EFR32FG 2400/868 MHz SLWRB4250B radio board (RS 122-9767) plugged directly into the mainboard. The radio board can also be used as a reference design for matching networks of the RF interfaces.
All debug functionality, including AEM, VCOM and PTI, can also be used towards an external device instead of the included radio board.
