1. Introduction
The EFR32FG23 Dev Kit has been designed to inspire customers to make battery operated IoT devices with the Silicon Labs
EFR32FG23 Wireless System-on-Chip. The highlights of the board include a segment LCD, an Si7021 relative humidity and tempera-
ture sensor, and an LC sensor for metal detection.
Programming the EFR32FG23 is easily done using a USB Micro-B cable and the on-board J-Link debugger. A USB virtual COM port
(VCOM) provides a serial connection to the target application, and the Packet Trace Interface (PTI) offers invaluable debug information
about transmitted and received packets in wireless links. The EFR32FG23 Dev Kit is supported in Simplicity Studio™, and a Board
Support Package (BSP) is provided to give application developers a flying start.
Energy profiling with advanced wireless network analysis and debugging are available through the provided Mini Simplicity Connector
using an external Silicon Labs debugger.
Connecting external hardware to the EFR32FG23 Dev Kit can be done using the breakout pads which present 16 GPIOs from the
EFR32FG23.
