MainBoard: common questions

What microcontroller does the MainBoard use?

The MainBoard is built around the ATtiny1606-S, from the AVR/Arduino family.

How big is the MainBoard PCB?

The MainBoard measures 100 × 40 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the MainBoard?

33 components, from 21 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 MainBoard design files?

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

Can I use the MainBoard design in my own project?

Yes, under the terms of its MIT license, which Finomnis chose for the repository.

Can I test firmware for the MainBoard without the hardware?

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