BG22-EK4108A

Silicon Laboratories - BG22-EK4108A

The BG22 Explorer Kit is an ultra-low-cost, small form factor development and evaluation platform focused on rapid prototyping and concept creation of Bluetooth LE IoT applications. It has been designed to inspire customers to make IoT devices with the Silicon Labs EFR32BG22 Wireless Gecko System-on-Chip. The kit includes a mikroBUS™ socket and Qwiic® connector, allowing users to add features to the kit with a large selection of off-the-shelf boards.
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 applications using a virtually endless combination of off-the-shelf boards from mikroE, sparkfun, AdaFruit, and Seeed Studios.
