Skadis clock: common questions

What microcontroller does the Skadis clock use?

The Skadis clock is built around the ATtiny2313-20S, from the AVR/Arduino family.

How big is the Skadis clock PCB?

The Skadis clock measures 327 × 95 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Skadis clock?

110 components, from 15 distinct parts. The full bill of materials is listed on this page.

Where can I download the Skadis clock design files?

From the agkaminski/hw_projects repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Skadis clock design in my own project?

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

Can I test firmware for the Skadis clock 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.
