C444: common questions

What microcontroller does the C444 use?

The C444 is built around the ATMEGA328P-PU, from the AVR/Arduino family.

How many components are on the C444?

50 components, from 25 distinct parts. The full bill of materials is listed on this page.

Where can I download the C444 design files?

From the hkstwk/c444 repository on GitHub, which has the schematic and a netlist; the links under Design files point to each one.

Can I use the C444 design in my own project?

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

Can I test firmware for the C444 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.
