Kicad: common questions

What microcontroller does the Kicad use?

The Kicad is built around the ATMEGA2560-16AU, from the AVR/Arduino family.

How many components are on the Kicad?

60 components, from 40 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Kicad design files?

From the harry123180/kicad repository on GitHub, which has the schematic and the BOM; the links under Design files point to each one.

Can I use the Kicad design in my own project?

The repository has no license, so all rights stay with harry123180. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Kicad 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.
