NRF5340 AUDIO DK Genel Bakış
The nRF5340 Audio Development Kit (DK) is the 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. The current consumption can be measured by using the dedicated current measurement pins. We recommend using Nordic’s Power Profiler Kit II for that. The new “Low Complexity Communications Codec” (LC3) that replaced Bluetooth Classic’s “Low Complexity Subband Codec” (SBC) is also available for this DK. 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.
