Note
Most Arduino interfaces are supported. Arduino pins D5 and D8 are not available, so arduino_gpio is disabled. On the EVK-NINA-B1, these pins are assigned to SWDIO and SWDCLK, respectively.
Other hardware features are not supported by the Zephyr kernel. See EVK-NINA-B1 product page 2 and NINA-B1 Data Sheet 3 for a complete list of EVK NINA-B1 hardware features.

LED0 (red) = P0.08
LED1 (green) = P0.16
LED2 (blue) = P0.18
General information on module pin numbering
The numbering of the pins on the module and EVK do not follow the GPIO numbering on the nRF52832 SoC. Please see the NINA-B1 Data Sheet 3 for information on how to map NINA-B1 pins to the pin numbering on the nRF52832 SoC.
The reason for this is the u-blox module family concept where different modules share the same pinout and can be interchanged, see NINA module family Nested design 4.
Programming and Debugging
Applications for the ubx_evkninab1_nrf52832 board configuration can be
built and flashed in the usual way (see Building an Application
and Run an Application for more details); however, the standard
debugging targets are not currently available.
Flashing
Build and flash applications as usual (see Building an Application and Run an Application for more details).
Here is an example for the Hello World application.
Open a terminal program to the USB Serial Port installed when connecting the board and listen for output.
Settings: 115200, 8N1, no flow control.
Then build and flash the application in the usual way.
