BinaryClock: common questions

What microcontroller does the BinaryClock use?

The BinaryClock is built around the ATMEGA328-AU, from the AVR/Arduino family.

How big is the BinaryClock PCB?

The BinaryClock measures 28.5 × 41.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the BinaryClock?

16 components, from 11 distinct parts. The full bill of materials is listed on this page.

Where can I download the BinaryClock design files?

From the JaredWright/BinaryClock repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the BinaryClock design in my own project?

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

Can I test firmware for the BinaryClock 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.
