Features Supported in Silicon Labs SDK for Zephyr#

SoCs#

Support for Series 2 SoCs is added incrementally. The platforms with the highest level of support are currently xG24 and xG29. Support is also available for xG22 and xG27. Community contributions have added support for xG21, xG23, and xG28.

Boards#

See the Silicon Labs board definitions in the Zephyr upstream documentation. To build for a specific board, pass the board name using the -b argument in the west build command.

You can use the Zephyr Supported Boards and Shields page to use the search tool to list the boards with definitions.

Wireless Protocols#

Series 2#

On Series 2 devices, only Bluetooth Low Energy (BLE) is supported. Community contributions have added support for custom RAIL configurations to enable proprietary wireless protocols.

Example Applications#

Example applications are available in the Zephyr upstream repository under Zephyr upstream Samples and Demos. These provide reference implementations for supported features and hardware.
