Nordic-powered module provides Bluetooth LE Audio connectivity for headphones, speakers & audio systems

Wireless communications company Rayson Technology has released a multiprotocol module based on Nordic Semiconductor’s nRF5340 System-on-Chip (SoC). The SoC is designed for advanced Bluetooth® LE Audio applications, as well as metering, wearable, smart home, industrial, and medical use cases. Measuring just 16.5 by 13.0 by 2.5 mm, the ‘BTM-N340X’ module supports LE Audio and its Low Complexity Communication Codec (LC3), which together enable higher quality, lower power wireless audio streaming compared with existing Classic Bluetooth audio solutions.

The module employs the nRF5340 SoC’s dual Arm Cortex-M33 processors – providing a high performance application processor capable of DSP and Floating Point (FP) alongside a fully programmable, ultra low power network processor. The application core manages the LC3 codec, while the Bluetooth LE protocol is supervised by the network processor.

Designed for wireless audio

“The BTM-N340X module has been designed for a wide range of applications, aiming in particular to provide enhanced audio experiences via Bluetooth LE Audio,” says Bob Wu, CTO at Rayson Technology. “It enables one device to stream audio to multiple pairs of wireless headphones, and can facilitate audio broadcasts through public address systems, such as in airports and museums. This module is also compatible with smart speakers and home audio systems.”
