Working with nRF54H Series

Note

All software for the nRF54H20 SoC is experimental, and hardware availability is restricted to the participants in the customer sampling program.

Information in this section complements the general Application development guides (such as Configuring and building or Programming an application) with information specific to devices of the nRF54H Series.

Zephyr and the nRF Connect SDK provide support and contain board definitions for developing on the following nRF54H Series device:

DK	PCA number	Build target
nRF54H20 DK	PCA10175	nrf54h20dk_nrf54h20_cpuapp nrf54h20dk_nrf54h20_cpurad nrf54h20dk_nrf54h20_cpuppr

Note

For details on the compatibility between nRF54H20 SoC binaries and nRF Connect SDK versions, see ABI Compatibility.
