Nrf52board: common questions

What microcontroller does the Nrf52board use?

The Nrf52board is built around the nrf52board, from the Nordic nRF family.

How big is the Nrf52board PCB?

The Nrf52board measures 27.9 × 59.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Nrf52board?

40 components, from 26 distinct parts. The full bill of materials is listed on this page.

Where can I download the Nrf52board design files?

From the dimka-rs/nrf52board repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Nrf52board design in my own project?

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

Can I test firmware for the Nrf52board 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.
