UG594: EFR32xG26 Explorer Kit User's
Guide
The EFR32xG26 Explorer Kit is an ultra-low cost, small form factor
development and evaluation platform for the EFR32MG26 Wire-
less System-on-Chip.
The EFR32xG26 Explorer Kit is focused on rapid prototyping and concept creation of IoT
applications. It is designed around the EFR32MG26 SoC, which is an ideal device family
for developing energy-friendly connected IoT applications.
The kit features a USB interface, an on-board SEGGER J-Link debugger, two user-LEDs
and two 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 proto-
type applications using a virtually endless combination of off-the-shelf boards from MIK-
ROE, SparkFun, Adafruit, and Seeed Studio.

- Page 6 UG594: EFR32xG26 Explorer Kit User's Guide Hardware 3. Hardware The core of the EFR32xG26 Explorer Kit is the EFR32MG26 Wireless System-on-Chip. Refer to section 1.4 Kit Hardware Layout placement and layout of the hardware components. 3.1 Block Diagram An overview of the EFR32xG26 Explorer Kit is illustrated in the figure below.
- Page 7 Wireless SoC Peripherals Figure 3.2. EFR32xG26 Explorer Kit Power Topology The 5 V power net on the USB bus is regulated down to 3.3 V using a low-dropout regulator (LDO). An automatic isolation circuit iso- lates the LDO when the USB cable is not plugged in.
- Page 8 3.5 On-board Debugger The EFR32xG26 Explorer Kit contains a microcontroller separate from the EFR32MG26 Wireless SoC that provides the user with an on-board J-Link debugger through the USB Type-C port. This microcontroller is referred to as the "on-board debugger", and is not pro- grammable by the user.
- Page 9 3.6 Connectors The EFR32xG26 Explorer Kit features a USB Type-C connector, 28 breakout pads, a mikroBUS connector for connecting mikroBUS add-on boards, and a Qwiic connector for connecting Qwiic Connect System hardware. The connectors are placed on the top side of the board, and their placement and pinout are shown in the figure below.
- Page 10 The pin-routing on the Wireless SoC is very flexible, so most peripherals can be routed to any pin. However, pins may be shared be- tween the breakout pads and other functions on the EFR32xG26 Explorer Kit. The table below includes an overview of the breakout pads and functionality that is shared with the kit.
