Rayson Technology Introduces Advanced Bluetooth Module with Nordic Semiconductor Technology for Superior Audio Connectivity

In a noteworthy development in wireless audio technology, Rayson Technology has announced the launch of its latest product, the BTM-N340X module. This innovative module, leveraging the power of Nordic Semiconductor's nRF5340 System-on-Chip (SoC), is poised to make a significant impact in the realms of Bluetooth Low Energy (LE) Audio, offering enhanced audio experiences and improved energy efficiency for an array of devices including headphones, speakers, and home audio systems.

The BTM-N340X distinguishes itself with its compact dimensions of just 16.5 by 13.0 by 2.5 mm, yet it brings remarkable capabilities to the table. Primarily focusing on Bluetooth LE Audio applications, the module uses the Low Complexity Communication Codec (LC3) to provide higher quality and lower power wireless audio streaming compared to traditional Classic Bluetooth audio solutions.

At the heart of the module's performance are the dual Arm Cortex-M33 processors included in the nRF5340 SoC. These processors are designed for high-performance applications, with one handling Digital Signal Processing (DSP) and Floating Point (FP) operations, and the other managing the Bluetooth LE protocol. This design enables the module to effectively manage the LC3 codec and oversee Bluetooth LE operations.

Bob Wu, Chief Technology Officer at Rayson Technology, emphasized the strengths of the nRF5340 SoC, stating, “In addition to the excellent technical capabilities of the chip, the high level of support from Nordic was a key factor when making our selection.”

The BTM-N340X module is not just limited to streaming audio to individual devices. According to Wu, “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.”

A significant feature of the BTM-N340X is its ultra-low power consumption, a critical factor in today's energy-conscious market. This efficiency is largely attributed to the nRF5340’s power-optimized multiprotocol radio, which boasts impressively low TX and RX currents and a sleep current of just 0.9 µA. Additionally, the independent operation of the module’s cores gives developers the flexibility to balance performance with power consumption, throughput, and low latency response.

To cater to various product applications, the BTM-N340X module is available with two antenna options: a pre-certified U.F.L Connector and a PCB pin out. It is also designed to operate within a broad temperature range of -40 to +85°C, making it suitable for diverse environments.

Wu further elaborated on the choice of the nRF5340 SoC for the module, highlighting its large memory capacity, radio sensitivity, and low power consumption as major advantages. The dual processors of the SoC, according to Wu, made it an ideal fit for the module’s LE Audio applications.

The launch of the BTM-N340X module is a significant step forward in wireless audio technology. Its combination of compact size, high performance, and low power consumption positions it as an attractive option for a wide range of audio applications. With the growing demand for advanced, energy-efficient Bluetooth LE Audio solutions, Rayson Technology's new offering is poised to meet these market needs, heralding a new era of enhanced audio experiences for consumers and opening new possibilities for developers in wireless communications.
