Working with 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	Build target	Documentation	Product pages
nRF9161 DK	PCA10153	nrf9161dk_nrf9161_ns	Product Specification User Guide	nRF9161 DK product page nRF9161 System in Package (SiP)
nRF9160 DK	PCA10090	nrf9160dk_nrf9160_ns	Product Specification Getting started User Guide	nRF9160 DK product page nRF9160 System in Package (SiP)
Thingy91	PCA20035	thingy91_nrf9160_ns	Getting started User Guide	Thingy:91 product page nRF9160 System in Package (SiP)

The nRF Connect SDK also offers samples dedicated to these devices.

To get started with an nRF9161 DK, complete the steps in the Quick Start app in nRF Connect for Desktop. For more advanced topics related to the nRF9161 DK, see the Developing with nRF9161 DK documentation.

If you want to go through a hands-on online training to familiarize yourself with cellular IoT technologies and development of cellular applications, enroll in the Cellular IoT Fundamentals course in the Nordic Developer Academy.
