EFR32xG28 Explorer Kit

The EFR32xG28 Explorer Kit is a small form factor development and evaluation platform based on the EFR32xG28 System-on-Chip. The EFR32xG28 Explorer Kit is focused on rapid prototyping and concept creation of IoT applications for Sub-GHz and Bluetooth LE like Wi-SUN, Amazon Sidewalk, Z-Wave, Wireless M-Bus, and proprietary networks.

Key features of the board includes a USB interface, an on-board SEGGER J-Link debugger, Packet Trace Interface, push buttons, and support for hardware add-on boards via a mikroBus socket and a Qwiic® connector. The hardware add-on support allows developers to create and prototype applications using a virtually endless combination of off-the-shelf boards from mikroE, sparkfun, AdaFruit, and Seeed Studios.
