Silicon Labs SiWG917Y Module Radio Boards

Silicon Labs SiWG917Y Module Radio Boards support Wi-Fi® 6 and BLUETOOTH® LE wireless IoT application development using Silicon Labs module-based radio board designs. The BRD4343C Radio Board is a plug-in board for the Wireless Pro Kit Mainboard, while the BRD4357C Radio Board is designed for co-processor evaluation via compatible adapter boards.

The Silicon Labs BRD4343C provides an evaluation path for the SiWG917Y-X Wi-Fi 6 and Bluetooth LE 8MB Flash Antenna Module with the Wireless Pro Kit ecosystem. The SiWG917Y Module Radio Boards also include BRD4357C support for the SiWN917Y-X Wi-Fi 6 and Bluetooth LE 4MB Flash Antenna Co-Processor Module, enabling host-connected development via SPI and SDIO adapter board options.

The boards are ideal for wireless IoT device development, Wi-Fi 6 connectivity, Bluetooth LE 5.4 applications, cloud-connected IoT systems, and host-processor-based co-processor designs. Software support includes Simplicity Studio, Energy Profiler, and Network Analyzer tools for application development, energy analysis, and wireless debugging.
