Developing with nRF91 Series

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 nRF91 Series.

Zephyr and the nRF Connect SDK provide support for developing cellular applications using the following nRF91 Series devices:

DK or Prototype platform	PCA number	Board targets	Documentation	Product pages
