ADM 52840: common questions

What microcontroller does the ADM 52840 use?

The ADM 52840 is built around the HolyIOT_NRF52840, from the Nordic nRF family.

How big is the ADM 52840 PCB?

The ADM 52840 measures 45 × 60 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ADM 52840?

41 components, from 30 distinct parts. The full bill of materials is listed on this page.

Where can I download the ADM 52840 design files?

From the Atelier-Du-Maker/ADM_52840 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the ADM 52840 design in my own project?

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

Can I test firmware for the ADM 52840 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.
