Note

The nRF5340 PDK has been deprecated with the introduction of the production-level nRF5340 DK. To determine if you have a PDK or DK, check the version number on the sticker on your kit. If the version is 0.11.0 or higher, the kit is an nRF5340 DK.

See the nRF Connect SDK v1.4.0 documentation for the last release supporting the nRF5340 PDK.

nRF5340 Audio DK is a custom reference hardware based on the nRF5340 DK. It is meant for use with for nRF5340 Audio applications, which integrate the LE Audio standard. Given their complexity, the applications use custom building and programming procedures. Refer to their documentation for more information.

The Nordic Thingy:53 is a battery-operated prototyping platform for IoT Systems. The Nordic Thingy:53 integrates the nRF5340 SoC that supports Bluetooth® Low Energy, IEEE 802.15.4 based protocols and Near Field Communication (NFC). The nRF5340 is augmented with the nRF21540 RF FEM (Front-end Module) Range extender that has an integrated power amplifier (PA)/low-noise amplifier (LNA) and nPM1100 Power Management IC (PMIC) that has an integrated dual-mode buck regulator and battery charger.
