.kicad: common questions

What microcontroller does the .kicad use?

The .kicad is built around the ATMEGA32U4, from the AVR/Arduino family.

How big is the .kicad PCB?

The .kicad measures 116.8 × 81.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the .kicad?

98 components, from 32 distinct parts. The full bill of materials is listed on this page.

Where can I download the .kicad design files?

From the hosier/free-of-charge repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the .kicad design in my own project?

Yes, under the terms of its MIT license, which hosier chose for the repository.

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.
