Bluetooth LE Audio – Better audio quality, longer playtime and new features
LE Audio is a newly introduced Bluetooth® standard designed for audio transmission. It operates on the Bluetooth® Low Energy radio and will change the way audio is experienced and consumed. Because of its low power consumption, the battery life of wireless audio devices will be significantly extended. Optionally, the size of those devices can also be drastically reduced. This new standard will also allow devices to mesh with Auracast™, where today's products can only connect two devices at a time. As a result, new ways of listening to music and new applications can be expected.
Getting started – nRF5340 Audio DK
The nRF5340 Audio Development Kit (DK) is the recommended platform for Bluetooth® LE audio products and supports all Auracast™ features. It includes everything needed to start development. The kit is configurable and can function as a USB dongle to send or receive audio data from a PC. It can also function as a business headset, a broadcast receiver, or a True Wireless Stereo (TWS) earbud. For most use cases, it is recommended to use two or more DKs. The three main components of this development kit are the nRF5340 SoC, the nPM1100 PMIC, and Cirrus Logic's CS47L63 audio DSP. The CS47L63's high performance DAC and differential output driver are optimized for direct connection to an external headphone load. It is ideal for mono-only headphones and direct speaker output. The nRF5340 Audio development kit is typically powered via USB and has a battery connector for a Li-Ion/Li-Po battery. The current consumption can be measured by using the dedicated current measurement pins. It is recommended to use Nordic's Power Profiler Kit II for that. The new "Low Complexity Communications Codec" (LC3), which replaced the "Low Complexity Subband Codec" (SBC) of Bluetooth® Classic, is also available for this development kit. The LC3 codec has superior audio quality compared to SBC, even at about half the wireless data rate. This low data rate is a key factor in minimizing the power consumption of your products.

Using the new nRF54H series to level up your BLE Audio device
The nRF54H20 is a compact, ultra-low power SoC with superior processing power, a generous memory, and excellent efficiency. It has a new best-in-class multiprotocol radio and state-of-the-art security features. Its unique combination of features, all integrated into a compact SoC, is ideal for creating innovative IoT applications that haven't been possible before. In addition to advanced wearables, smart home, medical, and LE audio applications, the nRF54H20 SoC also enables applications that require complex machine learning (ML) and support for sensor fusion at the edge.
The SoC's high level of integration enables developers to shrink their designs by replacing multiple components – such as the application MCU, external memory, and wireless SoC – with a single, highly compact device. In addition, its excellent energy efficiency enables the use of smaller batteries, further reducing design size and cost.

The nRF54L15 DK is the development kit for all three wireless SoC (System-on-Chip) options in the nRF54L Series. The nRF54L15 sits on the development board, while the nRF54L10 and nRF54L05 can be emulated. The affordable single-board development kit makes all features of the wireless SoC available to the developer.
The nPM1300 Evaluation Kit allows for simple evaluation and code-free configuration of the nPM1300 Power Management IC (PMIC). By connecting to the nPM PowerUP app found in nRF Connect for Desktop, all settings of the nPM1300 can easily be configured through an intuitive GUI and exported as code to be implemented in your MCUs application.
The nRF7002 DK is the development kit for the nRF7002, and nRF7001 Wi-Fi 6 Companion ICs. It contains everything needed to get started developing on a single board. The DK features an nRF5340 multiprotocol System-on-Chip (SoC) as a host processor for the nRF7002.
The Power Profiler Kit II (PPK2) is a standalone unit, which can measure and optionally supply currents all the way from sub-uA and as high as 1A on all Nordic DKs, in addition to external hardware.
The Nordic Thingy:53™ is an easy-to-use IoT prototyping platform. It makes it possible to create prototypes and proofs-of-concept without building custom hardware. The Thingy:53 is built around the nRF5340 SoC, our flagship dual-core wireless SoC. The processing power and memory size of its dual Arm Cortex-M33 processors enables it to run embedded machine learning (ML) models directly on the device.
The Nordic Thingy:91 X is a battery-operated prototyping platform for cellular IoT based on the nRF9151 System-in-Package (SiP) supporting LTE-M, NB-IoT, GNSS and NR+, and certified for global operation. It is the ideal platform for rapidly developing a prototype for any cellular IoT concept, and is especially suited for asset-tracking applications. Nordic Thingy:91 X enables location tracking using cellular (MCELL and SCELL), Wi-Fi, or GNSS, in combination with nRF Cloud Location Services.
The nRF9151 DK is an affordable, pre-certified single board development kit for evaluation and development on the nRF9151 System-in-Package (SiP) for LTE-M, NB-IoT, GNSS and DECT NR+. It has a dedicated LTE-M, NB-IoT and DECT NR+ antenna that supports a wide range of bands to operate globally.
