NRF5340-AUDIO-DK

NRF5340-AUDIO-DK is a nRF5340 Audio Development Kit (DK) recommended platform for Bluetooth “LE Audio” products and contains 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, we recommend using two or more DKs. The three main components of this DK are the nRF5340 SoC, 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 perfect for earbuds with mono-only and direct speaker output. The nRF5340 Audio DK is typically powered via USB and has a battery connector for a Li-Ion/Li-Po battery. Suitable for LE audio, headphones, hearing aids, audio guides, office headsets, audio broadcast solutions, conference speakerphones.
