Introducing the nRF5340 Audio DK
About the Kit
- Two 3.5 mm audio jacks for analog in and headphones out
- Five user-programmable buttons and LEDs
- SD-Card holder for extra storage if needed
- J4 connector for an NFC antenna
- SEGGER J-Link debugger for programming and debugging
- Connectors to access the analog/digital interfaces, and GPIOs
The nRF5340 SoC combines a high-performance application processor with a fully programmable ultra-low-power network processor. This dual core architecture allows for optimal power efficiency. The 128 MHz Arm® Cortex®-M33 Application Processor has 1 MB flash and 512 KB of RAM, which is perfect for handling custom applications and audio codecs, like LC3. The 64 MHz Arm Cortex-M33 Network Processor has 256 KB Flash and 64 KB RAM. It is power optimized to run Nordic’s Bluetooth LE Audio stack.nPM1100 PMIC
The nPM1100 power management IC has a highly efficient configurable buck regulator. It also includes an integrated battery charger with a charge current up to 400mA. It’s extremely small form factor makes it ideal for size-constrained applications like True Wireless Earbuds.nRF Connect SDK
The nRF Connect SDK is the software development kit for the nRF5340 SoC, and it has board support for the nRF5340 Audio DK. It supports the development of Bluetooth LE Audio, Bluetooth Low Energy, Thread, and other applications. The Zephyr RTOS, protocol stacks, samples, hardware drivers, and much more are integrated in the nRF Connect SDKnRF Connect SDK also supports the nRF9160, our LTE-M/NB-IoT/GPS SiP, and the nRF52 Series. It is a common platform for both cellular IoT and short-range development.
