ClockOmat: common questions

What microcontroller does the ClockOmat use?

The ClockOmat is built around the ATmega328P-AU, from the AVR/Arduino family.

How big is the ClockOmat PCB?

The ClockOmat measures 30.5 × 114.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ClockOmat?

92 components, from 24 distinct parts. The full bill of materials is listed on this page.

Where can I download the ClockOmat design files?

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

Can I use the ClockOmat design in my own project?

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

Can I test firmware for the ClockOmat 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.
