UG465: BGM220 Explorer Kit User's Guide
The BGM220 Explorer Kit is an ultra-low cost, small form factor
development and evaluation platform for the BGM220P Wireless
Gecko Bluetooth® Module.
The BGM220 Explorer Kit is focused on rapid prototyping and concept creation of IoT
applications. It is designed around the BGM220P Module, based on the EFR32BG22
System-on-Chip, which is an ideal device family for developing energy-friendly connec-
ted IoT applications.
The kit features a USB interface, an on-board SEGGER J-Link debugger, one user-LED
and button, 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 ap-
plications using a virtually endless combination of off-the-shelf boards from mikroE,
sparkfun, AdaFruit, and Seeed Studios.

UG465: BGM220 Explorer Kit User's Guide Hardware 3. Hardware The core of the BGM220 Explorer Kit is the BGM220P Wireless Gecko Bluetooth® Module. Refer to section 1.4 Kit Hardware Layout for placement and layout of the hardware components. 3.1 Block Diagram An overview of the BGM220 Explorer Kit is illustrated in the figure below. -
Page 7: Power Supply
Bluetooth Module Peripherals Figure 3.2. BGM220 Explorer Kit Power Topology The 5 volt power net on the USB bus is regulated down to 3.3 V using an LDO (low-dropout regulator). An automatic isolation circuit isolates the LDO when the USB cable is not plugged in. -
Page 8: On-Board Debugger
3.5 On-board Debugger The BGM220 Explorer Kit contains a microcontroller separate from the BGM220P Wireless Gecko that provides the user with an on- board J-Link debugger through the USB Micro-B port. This microcontroller is referred to as the "on-board debugger", and is not pro- grammable by the user. -
Page 9: Connectors
3.6 Connectors The BGM220 Explorer Kit features a USB Micro-B connector, 20 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: Breakout Pads
The pin-routing on the Wireless Gecko is very flexible, so most peripherals can be routed to any pin. However, pins may be shared between the breakout pads and other functions on the BGM220 Explorer Kit. The table below includes an overview of the breakout pads and functionality that is shared with the kit. -
Page 11: Mikrobus Socket
Qwiic connector, and all mikroBUS signals are also routed to adjacent breakout pads. When inserting a mikroBUS add-on board, refer to the orientation notch on the BGM220 Explorer Kit, shown in the figure below, to ensure correct orientation. -
Page 12: Qwiic Connector
The BGM220 Explorer Kit features a Qwiic® connector compatible with Qwiic Connect System hardware. The Qwiic connector provides an easy way to expand the functionality of the BGM220 Explorer Kit with sensors, LCDs, and other peripherals over the I C interface. -
Page 13: Debugging
4. Debugging The BGM220 Explorer Kit contains an on-board SEGGER J-Link Debugger that interfaces to the target BGM220P using the Serial Wire Debug (SWD) interface. The debugger allows the user to download code and debug applications running in the target BGM220P. Addi- tionally, it also provides a virtual COM port (VCOM) to the host computer that is connected to the target device's serial port, for general purpose communication between the running application and the host computer. -
