Nigun: common questions

What microcontroller does the Nigun use?

The Nigun is built around the ATSAMD21E, from the Microchip SAM family.

How big is the Nigun PCB?

The Nigun measures 54 × 50.1 mm and is 1.6 mm thick.

How many components are on the Nigun?

150 components, from 50 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 Nigun design files?

From the raziele/Nigun repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Nigun design in my own project?

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

Can I test firmware for the Nigun without the hardware?

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