The KiCad project lives in the anand2532/nRF9161-DEV-BOARD repository on GitHub; these links point at the commit this page was built from.

NRF9161-DEV-BOARD: common questions

What microcontroller does the NRF9161-DEV-BOARD use?

The NRF9161-DEV-BOARD is built around the NRF9161-LACA-R7, from the Nordic nRF family.

How big is the NRF9161-DEV-BOARD?

The NRF9161-DEV-BOARD measures 120 × 80 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the NRF9161-DEV-BOARD?

78 components, from 52 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the NRF9161-DEV-BOARD design files?

From the anand2532/nRF9161-DEV-BOARD repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the NRF9161-DEV-BOARD design in my own project?

The repository has no license, so all rights stay with anand2532. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the NRF9161-DEV-BOARD without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Nordic nRF firmware against it before you order a PCB.
