The Silicon Labs 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. 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.
