Hello,

I'd also recommend having a look at the SDK fundamentals course here: https://academy.nordicsemi.com/courses/nrf-connect-sdk-fundamentals/

and the getting started guide for the DK https://www.nordicsemi.com/Products/Development-hardware/nRF54L15-DK/GetStarted

nRF54L15 DK - Get started - nordicsemi.com

The nRF54L15 DK is the development kit for all three wireless SoC (System-on-Chip) options in the nRF54L Series. The nRF54L15 sits on the development board, while the nRF54L10 and nRF54L05 can be emulated. The affordable single-board development kit makes all features of the wireless SoC available to the developer. The nRF54L15 DK is supported by a comprehensive set of nRF Connect tools and ...

It sounds like you have been working with the DK, so the SD fundamental course will take you through parts of the steps needed to setup and work with your custom boards. The steps that Jay are referring to.

Best regards

Hi Liisa,

Yes, you can use the nRF54L15 DK board as the target board.

You’ll need to define your hardware in an overlay file and include it as a base device overlay when adding your build configuration.

In the overlay, you can disable unused peripherals (such as SPI, PWM, etc.) and enable only what you need, like I2C for a specific sensor.

However, keep in mind that you’ll need to review the DK’s configuration and DTS components to understand how they’re structured, so you can adapt them properly.

That’s all I can share from my experience.

Regards,
Jay
