Low-power Bluetooth 5.2 module for advanced applications
Based on the Nordic nRF5340 SoC, the Bluetooth modules support Isochronous Channels and LE Audio for next generation applications.

Laird Connectivity has announced the BL5340 Series of Bluetooth 5.2 and 802.15.4 modules, the latest addition to their multi-wireless portfolio. The modules are based on the nRF5340 system-on-chip (SoC) from Nordic Semiconductor and target high performance application areas such as industrial automation, asset tracking, smart building, and secure medical peripherals.

Leveraging the user accessible dual-core Arm® Cortex M33 microcontroller, the BL5340 is a true product platform for wireless connectivity. It allows wireless product designers to reduce the inevitable tradeoffs of how to efficiently support a network processor and a powerful performance processor for complex application enablement. One core can look after the more simplistic Bluetooth LE software operation and tasks, freeing up the application processor to be clocked as their application needs between 128 or 64 MHz. Each processor core supports their own power management systems software, eliminating stack and application code contention.

The BL5340 Series includes several module implementations of the nRF5340 – from integrated/external antenna options on the standard BL5340 option to the certified addition of Nordic's nRF21540 PA/LNA for customers looking for increased range and transmit power, for use in harsh industrial applications. The support for Isochronous Channels and LE Audio provides next generation Bluetooth audio capabilities, opening up new use cases for product designers with stereo streaming and broadcast audio applications.
