Support for the xG23-PK6068A board.
The EFR32xG23 (xG23) Pro Kit is designed to support the development of Wireless IoT devices based on Sub-GHz wireless protocols. The Pro Kit includes a radio board that provides a complete reference design for the EFR32xG23 Wireless SoC, with the matching network for +20 dBm covering 868 to 915 MHz.
The main board contains an onboard J-Link debugger with a Packet Trace Interface and a Virtual COM port, enabling application development and debugging of the attached radio board as well as external hardware through an expansion header.
