M128 clock: common questions

What microcontroller does the M128 clock use?

The M128 clock is built around the ATmega168A-P, from the AVR/Arduino family.

How big is the M128 clock PCB?

The M128 clock measures 95.8 × 81.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the M128 clock?

26 components, from 10 distinct parts. The full bill of materials is listed on this page.

Where can I download the M128 clock design files?

From the eshazen/epic-boards repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the M128 clock design in my own project?

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

Can I test firmware for the M128 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.
