SDK Series Directory
In June 2024, Silicon Labs introduced Simplicity SDK, an embedded software development platform for building IoT products based on Series 2 and upcoming Series 3 wireless and MCU devices.
Simplicity SDK is the successor to the widely adopted Gecko SDK, which will continue to be available providing long-term support for our Series 0 and Series 1 devices.
Explore the table below to learn how each device family maps into a device series.
